[ 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 was looking for a lightweight down mummy bag for spring/summer camping. Budget was pretty tight so stayed away from the Big Agnes etc. This bag is perfect down to about 35 degrees F. I suggest having a small blanket as well. Packs super small and looks good.

[ Very compact and most importantly down jacket. Purely for warm weather. in 2021 they replaced the down from 600 to 550. But from the positive they made a more practical decoration. And it was important to move the pocket under the phone in the middle( now it is bigger). Took it to replace a synthetic sleeping bag. In fact, the comfort temperature is close to 50 F. I would not recommend it for early spring or late fall.

It ’s comfortable, versatile, warm, and beautiful! ... For reference- I 'm 5' 4 '', and my toes do n't touch the bottom of this bag but I can stay plenty

smallplanepilot
[ 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!

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!

[ 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!

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.

[ I ’ m super impressed with the quality of this sleeping bag. It is beyond comfortable with duck down feathers that are safe to get wet. It has so many features for a sleeping bag such as, many different zippers, pockets, a phone holder. It folds up so small and compact. I love that they do field tests with their products before they sell them. Definitely high end quality.

[ The Sea to Summit Basecamp Down Sleeping Bag is like a cozy cocoon for chilly nights under the stars! Its 15°F/- 9°C rating will keep you snug even when the temperatures drop. What's impressive is how it manages to be incredibly warm while also feeling as light as a feather. You definitely won ’ t even notice the weight if you plan on hiking with this! The spacious design, adjustable hood, and draft opening in the bottom are thoughtful touches that promise a comfortable snooze. I ca n't wait to take it out on my summer adventures and experience firsthand how it delivers on warmth, comfort, and lightweight convenience!

[ Sea to Summit makes high- quality products and this sleeping bag is no exception. We already have a sleeping bag from this brand, so I didn ’ t have any doubts when ordering this one. It is super lightweight but very warm. All the detailing is precise and crafted perfectly. The sleeping bag is warm and it is very comfortable. The insulation is distributed evenly throughout the bag. it comes in this storage bag, but there ’s also an included attachment to clip it to your backpack. It doesn ’ t take a lot of space, but it can be even packed more tightly.

Motocamper
[ This bag is not 100% down which was initially somewhat disappointing, but it did a great job keeping me warm on a few 30 degree nights during a motorcycle camping trip. It packs small and light and feels like a high quality bag. If you 've never used a down bag, the amount it compresses is surprising and in my opinion worth the extra spend compared to their synthetic brethren. The snag free zippers seem to do their job well, too. I 'd buy it again!

[ 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.

[ I 've had my Kelty Galactic 30 for 5 years, and just bought a pair for my son and his wife. In my opinion this is the best bang for your buck in a sleeping bag for backpacking or camping. Packs small, lightweight, and reasonable price. It has a lot of loft and is very cozy. I sleep comfortably in it down to 40 degrees and add a liner to get to the mid- 30's, so it serves me well 3 seasons. I 've thrown it in the washer and dryer several times- just shake it out well and it regains its loft. Highly recommended!

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!

[ Exactly what I expected! Amazing quality materials and absolutely lightweight for travel- folds down easy for repacking!

Camping season can ’ t come soon enough!

[ 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!

[ 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

[ 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.

[ 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 am shocked at how soft and light this sleeping is. It keeps me warm and never gets hot. My body easily regulates its temperature. The bag is easy to fold up and place in its bag, which allows for the drying of material.

[ The color is lovely and storage bag is a wonderful bonus. It ’s so soft and warm and easy to move around in. Will be great for someone who sleeps on their side. My favorite part is that it goes around the face since I sleep with covers all the way to my head.

[ What an amazing sleeping bag!! It is so so warm, fluffy, and long! It really is super comfy to be bundled up in and I love that it has space to stretch out in. It is super easy to roll up into the case. I love that they not only included the case for it but also a smaller case that can be strapped onto a backpack! Great item! Camping season can ’ t come soon enough!

[ I received this product complimentary from Influenster and Sea to Summit. Spark may be the right bag for you. Filled with RDS- certified 850+ fillpower goose down treated with a non- PFC Ultra- Dry Down treatment, the Spark is constructed with a technical hood Extremely nice sleeping bag will definitely keep me warm during the cold winter months while outdoors.

[ 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 sleeping bag is absolutely amazing. It is super light to carry( brings a bag to carry in it). Also, it is so soft and warm. This will be great use for our upcoming camping trip. I ’ m so excited about sleeping in it. I ’ m 5 ’ 4 for reference and this is a regular size one. It fits perfectly and still has plenty of legroom.

They integrate perfectly and pack down better than anything else.

[ I used this as my sleep system for a long bike packing trip on the Katy Trail in Missouri. The packability and the warmth were perfect. I love the toe box being able to pull around my pad and the straps were perfect for keeping it in place. I did find I was most comfortable leaving the top strap off while sleeping. If you are going for ultra light and packable you will not beat this product. I would choose it every time.

[ 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!

[ 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.

[ 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.
Duck down sleeping bags are known for their excellent insulation properties, providing warmth without adding excessive weight. The natural down material is highly compressible, allowing for easy packing and transport, making it ideal for camping and backpacking. Additionally, duck down tends to be more affordable compared to goose down, offering a budget-friendly option for outdoor enthusiasts.
When selecting a duck down sleeping bag, consider the temperature rating based on the conditions you expect to encounter. Look for a bag that matches or exceeds the lowest temperatures you plan to camp in, keeping in mind your personal comfort preferences and any additional insulation layers you may use. It's also helpful to check the bag's fill power, as higher fill power generally indicates better insulation efficiency.
Key features to consider when choosing a duck down sleeping bag include the fill power, weight, and packability. Additionally, look for features like draft collars, hoods, and zippers that enhance warmth and comfort. Water-resistant or treated down can also be beneficial for moisture-prone environments, ensuring that the bag retains its insulating properties even in damp conditions.
Duck down sleeping bags can be suitable for various seasons, but their effectiveness largely depends on the temperature rating and design. For summer camping, lightweight and lower-temperature-rated bags are ideal, while colder seasons may require bags with higher insulation and features to retain warmth. Always consider the specific conditions and your personal comfort needs when selecting a sleeping bag for seasonal use.
Duck down sleeping bags generally offer superior warmth-to-weight ratios compared to synthetic options, making them lighter and more compressible. However, synthetic sleeping bags tend to perform better in wet conditions, as they retain insulation properties when damp. Ultimately, the choice between duck down and synthetic sleeping bags depends on your specific needs, such as weight, packability, and the expected weather conditions.
