Super comfortable. Feathers everywhere.

I have been using this bag for about a month now and I really love it. It keeps me warm and cozy and is a great partner for the Static V as well. It gets a bit clingy on your skin with moisture so I recommend sleeping in pants and socks. A good amount of room for moving around and I haven’t had much trouble with shoulders being too broad. My only main gripe is the feathers getting everywhere. They’re on my clothes when I wake up or caught in my leg hair and in the tent. I don’t know if that will stop after using it longer, but just a little annoying. Not enough for a low rating though because everything else about it is awesome!

I am not a huge fan of mummy bags because I like to move my legs while I sleep. Sometimes I wake up in a panic in other sleeping bags I have had because I have a hard time moving my legs. This sleeping bag has elastic baffles that make it easier to move around and find a comfortable sleeping position. A friend of mine told me about it and I absolutely HAD to have it. I haven't gone camping in it yet, but I am so excited to get to try it out. Update: I have gone camping in it and it's the bee's knees.

This bag packs so small! I’m used to having something 3 times this size and I love how much easier this is for backpacking. The second zip by the feet is awesome to let in a breeze when it’s a little warmer out. Love the hooks to bring the sleeping bag smaller for shorter people. Very smart design! The accordion style to it is amazing. Keeps more warmth in without having to stuff all of my clothes to my feet. Fantastic bag!

Great cool weather bag

The size of this sleeping bag is fantastic. Very small and lightweight. I’ve used it for several months including nights that got down to 17 degrees. Only thing I did then was put a fleece blanket inside just so there was some moisture wicking. I have never slept so warm with any sleeping bag I’ve ever owned. I love the second zipper for my feet when it does get warm. It’s fantastic to have a breeze at my feet.

I have slept in this bag on two week long hiking trips where night temps got to low 30s and a couple weekend in a cabin w low temps and in a tent camper. Very comfortable, the baffle system is great. Have used many bags and for the weight and cost my favorite. I do recommend getting a good dry bag for it as hiking out we got dumped on and the bag got soaked and took a long time to dry out.

Great bag

Very happy with this bag, and to be honest, it's the first bag I've owned that I would say is under-rated for temperature. Accordion design is fantastic, what a great expansion of the mummy style benefits to those that typically don't prefer them. Durable material that's initially cold, but warms quickly into a super warm, soft and comfortable bed. Have taken backpacking and camping in multiple areas of CO, absolutely a great decision to purchase. Got one for my son as a gift because I was so pleased.

Durable warm sleeping bag for the back country of Montana

This sleeping bag should first on the list for best backcountry sleeping bags. Its warm and when paired with a liner it can be used in very cold rough conditions. I love it so much and keeps me warm on walks during late fall when i go to bed down for the night. Would 10/10 recommend to anyone looking to use it for the same purpose. Doesn't get much better than this.

Great Bag!

Got this bag a couple months ago and it has worked great every camping trip Ive gone on since then. Switch from synthetic bag and man there is a night and day difference. Super lightweight and super warm. Only problem is the down leaks out quite a bit but not so much that it's a concern.

Klymit KSB 20

I have never liked mummy style sleeping bags because of how restricted you feel inside. The baffle technology incorporated with the Klymit KSB 20 allows you to move around. It is lightweight yet feels durable enough to withstand the rigors of hiking and camping. Well done! I will definitely be purchasing a second bag.

Exactly what I wanted

This bag has everything I look for in a sleeping bag. I'm a side sleeper so I've never been a huge fan of mummy bags, but the flexible baffles give me all the leg room to toss and turn and the draft collar gives all the warmth of a mummy bag. It's an added bonus that it is lightweight and easy to pack.

Don't let anyone borrow it

I've been using this bag for a couple years. The baffles are perfect for someone that rolls over in the night, or stretches, or doesn't like the restriction of a typical mummy bag. Then I let my wife use it this summer when I opted for a lighter bag on a trip. She won't give it back.

At 45 deg, it's not too bad. even less than 16 deg, no problem. From unexpected camps on bare ground at 12,000 ft, to summer backpacking, this bag can do it all. It's lightweight, extremely packable, and impressively durable.

Light weight. The leg area is flexible so you can move around without feeling like your tied up. The chest area is a little tight on wide shoulder men. So if your on the muscular or big size i would go with the oversize bag. Make sure to air out and store in mesh bag when not using.

Sleep warm

Camped out in October of 2019 near Sedona, AZ, and went MTB riding. the bag was Comfortable, slept warm. I had a light weight pad under the bag. The temps were in the low 40's at night and I actually got a little warm and had to unzip the bag some during the night.

Really Sweet Bag

I've been sleeping in this bag every night for the last few weeks. I love it. It's warm as hell, the zipper almost never catches, and I've only noticed one stray down feather up to this point.

Warm and cozy

Slept in 20 degree weather in the mountains during the winter and this bag kept me warm I ended up sweating and was soft easy to pack light to carry and cozy as it hugged against me but not tight

As promised

Packs very well. Extremely comfortable on the skin. Hood is functional to prevent heat loss from the neck and head. Bevels work quite well to save bulk. Works well in a camping hammock due to shape.

toasty toes!

I love the fact that you can adjust the length. I am a cold sleep with cold feet and being able to shorten the bag with the toggles gave me extra warm feet with all the extra down !

the warmth and weight are awesome. i used it for a solid monthe in the Colorado back country. I would give it a 10 but it seemed to loose a few more feathers than ones I have had in the past

Comfortable, Packable, Reliable

This is my go-to mild to cold weather bag. EXTREMELY comfortable and has kept me warm to 15°. Very well thought out product from the generous baffle to prevent cold air getting in, to the adjustable length of the bag to make it fit for you.

Super Warm

Nice bag.. lightweight, but warm! Love the how it stretches around the feet.. don't feel so wrapped up in it. Packs down small as well. 5 stars!

Perfect sleeping bag.

I used this bag during the fall and winter months a desert environment. I would recommend this as a great all-around lightweight sleeping bag.

So far so good

I haven’t been camping in this yet. Don’t judge, but I have been using this as a blanket when I watch movies. High quality, very comfy and I can’t wait to take it winter camping.

Great buy for the price

Comfortable and warm. Had to push a lot of down around the baffles right after purchase, and it has a minor tendency to lose feathers faster than others I've used.

I love this bag. Used 150+ nights last year and cant complain. Very comfortable and so far the zippers have held up and don't snag often.
