This sleeping bag is not only very warm( outside temp at approx 40F) but is manageable at warmer conditions when not zipped all the way up( outside temps at 60F) I 'm extremely satisfied with the bag

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.

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.

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.

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 a stomach sleeper, and the idea of having a central zip for ease of in/out and minimal zipper appealed to me. ... Incredibly warm and super

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.

[ I can not wait to take this bag on the Arizona Trail this year. 900 fill goose down. I 'm sorry but I am not a `` quilt guy ''. I enjoy the mummy shape. It is my favorite bag.

[ 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 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 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 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.

[ The sea to summit traveller is an all around winner for us! I love the color 😂, but for practical reasons it kept me warm and didn ’ t weigh me down! No pun intended. Can be packed back into its small carry pouch and stowed in/on most any pack. Super happy with this one!

[ So I got this traveller size down sleeping bag for free to review and I used it one time in my backyard and it ’s so warm and comfortable I would definitely recommend this to anyone
$449.00-$479.00
It ’s very comfortable to sleep in, and I really appreciated the option to connect it to another bag. ... Comfortable, warm, adjustable ... The material is super soft and doesn ’ t sound scratchy so it ’s not noisy when rolling

[ 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.

[ Man, this was a great claim now!!! I chose a sleeping bag that seemed to have variable uses, cuz I am not much of a camper, but man this thing is comfy and warm. Cant wait to use it in multiple climates.

[ 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 bought this bag as a Christmas gift for my son. It is fantastic. I love the different features it has. Such as the dual zipper, the little stash pouch for your head lamp or flashlight, and the material. My son now only wants to sleep in the sleeping bag instead of his bed.

[ Bought this about a month or two back, have used it on three over night trips now... Sleeps comfortably in all conditions, my evening in the upper 30 ’s I stayed toasty and warm. And this past weekend in the 60 ’s, I wasn ’ t too hot. Rather perfect temperature in each sleep. Highly suggest the bag at this price point.

[ Great bag! Lightweight comfy and packs down good. I bought as a summer bag for multiple backpacking trips in the cascades and it worked out perfect.
When choosing an expedition sleeping bag, consider features such as insulation type, temperature rating, and weight. Down insulation is often preferred for its warmth-to-weight ratio, while synthetic options may perform better in wet conditions. Additionally, look for a design that includes a draft collar and hood for added warmth, as well as a durable outer shell to withstand harsh environments.
The right temperature rating for an expedition sleeping bag depends on the conditions you expect to encounter. It's important to consider both the lowest temperatures you might face and your personal comfort level. A sleeping bag with a lower temperature rating will provide more warmth, but you should also factor in the insulation type and your sleeping habits to ensure a good night's sleep.
Expedition sleeping bags are typically made from either down or synthetic materials. Down is known for its excellent insulation properties and compressibility, making it lightweight and easy to pack. Synthetic materials, on the other hand, offer better moisture resistance and retain warmth even when wet, making them a practical choice for unpredictable weather conditions.
Yes, there are different styles of expedition sleeping bags designed for various activities and environments. Some bags are tailored for extreme cold, while others are more suitable for milder conditions. Additionally, features like zipper length, shape (mummy vs. rectangular), and added ventilation options can cater to specific uses, such as mountaineering, backpacking, or camping.
The weight of an expedition sleeping bag is crucial for long treks, as it directly impacts your overall pack weight and comfort during travel. Lighter bags are easier to carry, especially over long distances, but it's essential to balance weight with warmth and durability. Opting for a sleeping bag that offers a good warmth-to-weight ratio can enhance your experience without compromising on comfort.
Durability is a key factor when selecting an expedition sleeping bag, as it needs to withstand rugged conditions and frequent use. Look for bags made with high-quality fabrics that resist abrasions and tears, as well as reinforced seams. Additionally, consider the bag's insulation type and how it holds up over time, especially in challenging environments where wear and tear are more likely.
