[ Holy moly is this sleeping bag amazing!! This is lightweight to carry making transport a breeze. The zippers are durable and don ’ t snag when zipping up. I love the contour and that it ’s specifically made for the female shape. The mummy design is meant to keep you toast and covered from the elements. I looove the zipper at the bottom to allow your feet out! Def for the intense campers!

[ I received this ascent women's down sleeping bag free from seatosummit and influenster in exchange for an honest review. I ca n't express how excited I am to take this on my next camping trip. This sleeping bag is so light weight and comfortable! It comes with a travel bag that is easy to store the sleeping bag to travel with. I am 5 '' 5 and weigh 220lbs and I fit perfectly with some room. Extremely comfortable and cozy. I love that it allows you to zip with another sleeping bag making it perfect for my husband and I. There are vents you can open if it gets too hot. Zippers and material feel very durable. I love the quality craftsmanship that went into making this product. They use non PFC and are RDS down certified. I am so impressed with this sleeping bag. I will be buying another one for my husband. I would 100 percent recommend this brand and product to all my friends and family.

I purchased 2 of the Nanowave 25 ’s and put them to the test in mid 30 degree weather with no additional blankets or sleeping bag liner. Impressed! Is all I will say! We woke up to ice on the perimeter of the tent and was nice and warm only utilizing the sleeping bag and a rolled up sweater as a pillow for 2 nights.

HappyCamp
[ This is a great 3 season bag! Light and packable for a synthetic. Very roomy. At six feet tall, 180 pounds, 34 waist, large hips and broad shoulders, I had plenty of room to sleep on my back and side. I had no problem with length even with my air pillow tucked into the hood. The temperature rating on the bag felt good in 30°F weather, keeping me nice and warm, paired with a sleeping pad rated at 4. 1 R value. A nice soft feel and glow in the dark zipper pulls are also good bonuses.

[ This sleeping bag is amazing! It is extremely warm and will keep you toasty on those cold nights outdoors. It fit me perfect with some extra room with a height of 5ft. It is on the larger side and they give a small bag to pack it in which is very difficult to get it in. They also include testing results on the down goose and duck feathers they use to insulate it. Definitely worth the buy!

elizabethr1983
[ This sleeping bag is the real deal! Let me tell you, I ’ ve put it through the wringer on a bunch of camping trips, and it's come out on top every single time. The durability of this thing is seriously impressive. I ’ ve treated it pretty rough, tossing it around, stuffing it into tight spots, and it still looks and performs like it ’s fresh out of the box. And let's talk about comfort. Oh boy, this bag is next- level cozy. I ’ m talking about sinking into a plush cloud kind of comfort. It ’s like a warm hug after a long day of hiking. I ’ m usually tossing and turning when I ’ m camping, but not with this bad boy. I slept like a log, no kidding. It fit me wonderfully! Now, let ’s get into packability. This is where this bag really shines. I ’ m all about saving space, especially when I ’ m packing for a camping trip. And let me tell you, this bag packs down like a dream. It squishes down nice and small, taking up hardly any room in my pack. It ’s a game- changer for sure. And the insulation? It ’s top- notch. I ’ ve used this bag in all kinds of weather conditions, from chilly nights to downright freezing ones, and it ’s never let me down. I ’ m talking about staying warm and cozy even when the temperature drops below freezing. No need for extra layers or anything like that. Overall, if you ’ re in the market for a sleeping bag that ticks all the boxes, this one ’s a winner. It ’s durable as heck, ridiculously comfortable, packs up like a champ, and keeps you warm when it matters most. Trust me, you won ’ t regret it

zarachristine
[ This sleeping bag is amazing! It ’s so soft and lightweight so very easy to hike/backpack/camp with. Despite being so lightweight the dense down feather inside of it allows for a lot of warmth! I love how it hugs my body perfectly keeping me nice and insulated.

[ I was sent this product in return for giving my honest opinion about it. The Sea to Summit Spark sleeping bag is a lightweight and compact sleeping bag that would be perfect for backpacking because it is so light. It has down insulation for warmth. I like that it has a hood it makes me feel covered really well. When I tried it out it wasn ’ t very cold but after a few minutes I was sweating so I could see how this would be great in very cold conditions.
$449.00-$479.00

[ Bought this sleeping bag a month ago for a backpacking trip in the Porcupine Mountains, and it performed wonderfully. It was warm, light, and packed down well. As a side sleeper, having plenty of room to toss and turn was amazing and made my sleep so much better. The best feature about it though is that there's a zip on either side so you can fold the top down like a blanket. Even better is that there's a snap closure at the top of each zip so you can unzip it, snap the closures, and wear the sleeping bag like a sleeveless snuggie. It's awesome.

[ My research told me, as I weigh 112 pounds, my pack should weigh around 22- 23 pounds. Trying to get all essentials in such a light pack, I was, as Colin Fletcher, author of The Complete Walker said, `` cutting off the tea bag labels ''. How GREAT to find a warm, comfy, COMFY sleeping bag that tipped the scales at only slightly over one pound! And at 79 years of age, I do n't want to develop a stoop in my walk!
5
Sheridan B.
I absolutely love this bag. I stay far warmer in this bag in colder temperatures than I have with zero degree bags in the past. It's certainly not the lightest 15 degree bag, but I 've found the little bit of extra weight to be well worth it for the warmth provided as well as the versatility of the zippers for the nights that are n't quite as cold. No complaints!

[ Purchased this bag for shoulder season backpacking in Colorado. I used it for the firsttime last weekend. Night time temps got down to around 28F and this bag kept me toasty and feeling warm all through the night. It is incredibly light weight considering the fill and has a nice feel to the material. The only thing I would change is to have the secondary foot zipper extend further into the foot box area. It does n't expel heat fast enough if you run warm.

After hours of research, I decided on and purchased the Nemo Tempo 20 men ’s regular spoon sleeping bag specifically for our trip to Grand Teton and Yellowstone National Parks as we car camped for 5 nights. While it was mid- May, night temps can drop into the low 30 ’s. Admittedly, I made my purchase from a third party, as I was skeptical about the quality and warmth factor. I am a 5 ’ 8 ” woman and wanted to be sure I had enough length to be comfortable so I opted for the men ’s Tempo. The fit was great and it was very comfortable. Didn ’ t bind or twist when I repositioned throughout the night. But the most important thing is it kept me very warm. Nighttime temps dipped into mid- 30 ’s. I only wore base layer leggings and top, no socks and my feet stayed toasty warm. In fact, I got so warm that I had to unzip the bag to regulate my body temp. It is well made and performs as advertised. It exceeded my expectations! I highly recommend Nemo Tempo 20!

I took this bag with me for a climbing trip down in bishop. The long bag is the perfect length for me( I 'm 6' 1) and provides plenty of width in essential areas like the shoulders and leg area. Temperatures on my trip gradually decreased as my trip went on, starting at 30- degree nights and dropping down to 18- degree nights towards the end of the trip. I would say the comfortability range is around the 27 to 30- degree mark. Once it dropped below 25, I started to get a little colder. If you want to use this bag in sub- 30- degree weather, I would recommend a fleece and a hoodie to make it a more comfortable night. Overall, this is a great bag and it did not disappoint. The tech specs advertised were pretty spot on as far as temperature rating. If you 're looking for a good sleeping bag for an affordable price, this is the one.

The Questar is my favorite ever sleeping bag, and I 've slept in a lot of sleeping bags. It's roomy enough to sleep in night after night, but light and packable enough to take on my next fast- and- light endeavors. The level of comfort is unparalleled- think silk pajamas- and the `` '' Toe- asis '' '' foot box( which took me a few nights to discover) is insanely cozy. I felt so warm and secure each night in this bag. Plus, having the knowledge that the down is hydrophobic( and that the outer fabric beads water) is a HUGE feeling of security, letting me sleep out under the stars without the threat of dew.
5
Lance R.
The Questar covers such a wide temperature range that it has come with me on winter- camping ski trips(< 20°F) as well as beach- camping surf trips(> 55°F). On the coldest nights I layer it with a quilt to give it that fourth season warmth, and on the hottest nights I sleep with it unzipped to get some breeze. The soft interior fabric is super comfy for those nights when minimal base- layering is needed. I 'm really excited to test the outer fabric and hydrophobic down with some ocean spray while camping on the coast sans tent/bivy this summer.
5
S.H
This is definitely one of my best purchases. I love the fact that this is hydrophobic down sleeping bag because on the pacific coast where I do most of my camping, I found that down bags soak up too much moisture and loose their heat retention and are heavier to carry.

Happy H.
I 'm 6 ft tall and weigh about 250 lbs. This bag has plenty of room in it. I LOVE the straps. They solve the slipperiness problem lots of people complain about with the Uberlight Pad. I 'm a side sleeper that tosses and turns and I did n't have a problem at all with this bag. Keeps me warm down to the mid 20s with no problem. Only had on a pair of light nylon shorts and a knit cap. Love the foot box. You can put socks and long underwear down in there and it keeps it warm and will help it dry out overnight and you do n't have to have your feet directly on them. Great bag. Thinking I 'll order the 32 degree version for summers.

The Bantamweight bag fits a wide range of temperatures and conditions. Its a very lightweight and compact performance sleeping bag. Ive used this for multi- day alpine routes and camping in a tent. Temperatures ranged from 0 degrees to 40 degrees F. I use this bag a lot for travel to save space and weight. For very low temperatures( while climbing a big mountain for instance), I wear a jacket while sleeping. Attached is a gear testing video of the Bantamweight with an adjustable footbox. Though not included in the production model, that particular feature is included in other marmot bags.

Cozy and warm. No room if you want to bring in your boot liners. Pretty tight for a big guy( across the shoulders) and similarly tough to get into the bag with the short zipper. Beautiful bag and super compressible.

nlhiker
[ This is a very nice bag, recommended as a basic tool for all kinds of spring/summer/fall mountain adventures. I 've used a bag like this( from another manufacturer, also with a half zipper) for nearly thirty years, and needed another for trips with my son. This one looks as good or better. I 've also used a variety of quilts and lighter bags. These can be fine for low- altitude midsummer trips such as the Appalachian Trail south of Vermont, or minimum temperatures above 50F. However, somewhere below 50F, you want a hood. `` 20F '' quilts of all sorts lack a hood, and are n't much lighter either. Very light weight is optimized here, with the use of a half- zipper and also a tight cut. Some people may prefer the comfort of a looser bag with a full zipper. This bag is warm enough for the occasional early- morning dip below freezing, but I would take something heavier if regular temperatures in the 20s are expected.

[ I purchased this bag a month ago for a trip to Banff. As I get more and more invested in spending quality time out in nature, I feel a deeper and deeper responsibility to purchase only products that have the highest quality of eco/sustainability( plus cruelty free when can!) This sleeping bag was the best one I could find on the market right now! Was perfectly comfy and warm, and it compressed down super well — easily fit into my carry on since I flew into Canada.

[ This sleeping bag is the best that I ’ ve ever tried. It is very lightweight but super warm. I like how easy it is to pack it up. It fits nicely in its own carrying bag, but it can be pressed even more to fit it in an even smaller space. There ’s plenty of room inside, but it is not so big that it wouldn ’ t function properly. It is very comfortable and easy to zip into it. Even my dog was obsessed with it when I first unpacked it

This is the 5th Trestles I 've bought for my family. It's just the right compromise on weight, warmth, and cost for high alpine trips into the Beartooth Mountains. All of them have been used in expedition weight tents, so they have been easily warm enough. This year I bought a Marmot Force ultralight backpacking tent and put my Trestles to the test of its limits. It performed admirably even with the drafty nature of ultralight tents. We had a couple of windy nights down into the 30's, which get a laugh from expedition weight 4- season tents, but I mummy'ed up in my Trestles 15 and was amazed at the comfort, roominess, and functionality!! I would n't still be buying them and on number 5 if it were n't for the great performance.

GREAT bag. I 've had for nearly two years now and still like new. I 've use it with my ultralight three season tent in- 20 and- 10 truly testing the limits but always feel warm and cozy. My only issue is it does n't pack as small as I 'd like for multiday trips, but purchasing a compression bag helps. Overall, beyond amazing for the price.

My roommate and I each bought this sleeping bag for a camping trip in the Upper Peninsula in September. Temperatures dropped to the low 30's and we stayed very warm and dry. Very compact, convenient pockets for phones/small belongings, full zippers. We both highly recommend!

Bought this just before a trip out to Washington in the fall. I am 5 ’ 6 ” and 120L and had no issues with being cold in temps around 35- 40°. Also the bag was plenty long for me with still about 2- 3 ” of room to spare( I bought the regular length bag). I did try this bag out when the temp was right around 30° and did get a little chilly( could have probably been fixed if I had a liner to go with the bag). I do wish it could compress just a little more but it does have a nice compression bag that comes with it. I would definitely recommend this to anyone looking for a cooler weather bag for a good value!!

[ Leveled up from my old synthetic sleeping bag to down and am super happy so far. It ’s so cozy and packs down small. I love that there ’s room for me to turn any which way and curl my legs up in this bag, it is much less constricting than a typical mummy bag. I did find that the bag didn ’ t really move with me the way I expected it to for side sleeping, so I found the hood section kind of in my way at some points. It wasn ’ t too cold so I just kept my head out and used that part as a pillow of sorts. I did also notice a bit of shedding of feathers and hope that will remain minimal over time. So far I ’ ve used it for two nights in about 40deg weather and was very warm.

I bought this bag for summer camping in the Colorado high country. I already have a 0 bag from Big Agnes so I needed something that would n't be so warm. I am a side sleeper and this seemed like the perfect bag. It's comfy, I love the fabric and I like the space for my knees when I sleep on my side. I also really love the hood. My only two criticisms are that the bag is a bit tight so I do n't feel like I can really spread out. My knees hit one side while my bottom hits the other. I also like to sleep with something between my knees and there is n't much room for that. My other issue is that when you turn over you either have to flip the entire bag with you or turn the other way so that your knees do n't fit into the shape of the bag. Flipping the entire bag over would be fine if I had a lot of space but when you have your bag on a ground pad and sleeping next to other people you ca n't really roll side to side. This bag is lightweight and silky though.

The Women's Long 15 is nearly identical to the unisex 0 degree regular bag if you looked at the sizing, weight and most importantly fill weight which is why it's larger. M's bags are rated to the Lower Limit and Women's to the Comfort limit. Hence they 're a bit like comparing an apple to an orange. Some hearty women may sleep differently but that's how the ratings system is set up.

Have n't tested this bag is 15 degrees yet but it was so cozy at 30 without having to layer up to sleep. This is my first time purchasing a women's sleeping bag and I am so so happy with the fit! Not really long past my feet so they stay warmer and it's a little roomier in the hips so I did n't get too tangled up. Does n't pack quite as small as other bags I 've seen, but ca n't beat it for the price! Love this bag!

Adult hybrid 30 sleeping bag is a great bag at a very reasonable price point. The relaxed mummy shape is perfect. The bag is very warm yet lightweight and the two way zipper allows you to let your feet out if needed for cooling. Love the fabric and the gorgeous teal color of the bag. What stood out was that it was not very noisy as some bags of this material are noisy. At 5 ’ 8 ” this bag was perfect for my height. Any taller though and you would be completely filling the hood to foot of the bag! A nice little extra is the little Velcro top pocket inside for keys or anything valuable. I also liked the extra feature of the clip on cover for the top of the bag to prevent dirt or water getting into the drawstring carry bag. This bag is perfect for our family camping trips and Cub Scout camp outs!

The tag says it can fit up to 6 ’ 5 ” but I feel like it might be a little snug for someone taller than 6 ft. I love that this is a thinner compact sleeping bag that keeps you warm. The fabric is nice and silky and the hood is big enough to cover your head. I ’ m going to keep it in my car for emergencies. Overall, I recommend you try this sleeping bag!

[ I love this sleeping bag! I typically go camping more casually, as in not backpacking for multiple days, etc., so keep that in mind when considering my opinion. The sleeping bag is lightweight yet warm. I ’ m glad it unzips on either side and includes various snaps and loops for increased functionality. I am an average height female of slim stature but I chose to purchase this version instead of the women ’s version. I haven ’ t compared sizes or other specs, but figured the unisex version was a safer and more flexible bet. I picked the 30 degree sleeping bag again for flexibility. I ’ ll be able to layer within the sleeping bag if I happen to camp in colder weather. I love the vented storage bag( as pictured). Not all sleeping bag storage bags are vented and that ’s a big positive for me.

I bought this sleeping bag for warmer weather where my 10 degree bag would be too uncomfortable. I figured to test the bag to its rating to get an idea of its performance. Weather said low for the night would be 45, so perfect time to test. I used this in a Kelty Tanglewood 2, with an Extremus( R- value 3. 0) sleeping pad and a very thin ozark trail sleeping bag liner. Had lightweight nylon pants and a lightweight sweatshirt on. The temperature got down to 37 and I was not cold, not super warm but with the shoulder draw string tightened up I was comfortable. I would n't take it much colder than that. I sleep a little on the warm side so that may have helped, but to me the sleeping bag lives up to the rating.

Low temperature sleeping bags are designed to provide insulation and warmth in colder conditions, making them ideal for camping or backpacking in chilly environments. They typically feature materials that trap heat while remaining lightweight and compressible for easy transport. Additionally, these bags often come with draft collars and hoods to minimize heat loss, ensuring a more comfortable night's sleep in low temperatures.
Low temperature sleeping bags are often made from synthetic fibers or down insulation, each offering unique benefits. Synthetic materials tend to be more water-resistant and maintain warmth even when wet, while down insulation is known for its superior warmth-to-weight ratio and compressibility. The choice of material can significantly affect the bag's performance, durability, and overall comfort.
When selecting a low temperature sleeping bag, consider factors such as the expected weather conditions, your body temperature regulation, and the bag's weight and packability. Look for temperature ratings that align with your planned activities, and think about the fit and features that will enhance your comfort, such as zippers, hoods, and draft protection. It's also helpful to read reviews and compare different models to find the best option for your adventures.
While low temperature sleeping bags are primarily designed for cold weather, they can be used in warmer conditions with some considerations. If the temperature is significantly higher than the bag's rating, you may find it too warm and uncomfortable. Some bags come with features like adjustable ventilation or removable liners that can help regulate temperature, making them more versatile for varying climates.
Low temperature sleeping bags generally have temperature ratings that range from around 20°F to -20°F, depending on the intended use and insulation type. These ratings indicate the lowest temperature at which the bag is designed to keep an average sleeper warm. It's important to choose a bag with a rating that matches the conditions you expect to encounter during your outdoor activities.
To maintain the performance and longevity of your low temperature sleeping bag, it's best to store it uncompressed in a cool, dry place. Avoid keeping it in its stuff sack for extended periods, as this can damage the insulation. Instead, use a larger storage sack or hang it up to ensure the filling retains its loft and insulating properties.
