Product Reviews

Rated 5 out of 5 by from Stellar Bag [This review was collected as part of a promotion.] This bag is top-notch. I used it for backcountry high alpine hunting in Idaho late season, with temps dipping down into single digits. It kept me totally warm. Very comfortable. I would not recommend using the pillow lock system, it caused severe damage to my bag. S2S replaced my entire bag though after the damage, excellent customer service.

Rated 5 out of 5 by from Cookoo for Cocoa Puffs [This review was collected as part of a promotion.] Great bag. Temp ratings accurate and bag feels very comfortable and snug but spacious. Only thing that took a little getting used to was the zippers felt awkward to me at first but no big deal

Rated 5 out of 5 by from This is the one [This review was collected as part of a promotion.] I spend way too much time diligently researching my gear purchases. After many hours (okay, days) looking for a 0 degree for backpacking, I landed on this one. I'm 100% happy with it. The liner is plush and super comfy, it packs down small, and the zippers allow to vent when it's too warm. I don't have trouble with the zippers. I am a restless sleeper and I love being able to sleep in all positions in this bag. Yes, it is 5-8 ounces heavier than the ultralight options, but so worth it. I spend 2 weeks at a time I'm the field for work and this bag makes a huge difference. I've used it at 20-40 degree temps so far. At 40 I was all the way unzipped. At 32 I had the short zipper undone. At 20 I was comfy, and I would be confident bringing this bag to 0.

Rated 4 out of 5 by from Excellent bag [This review was collected as part of a promotion.] First time using a sleeping bag at this price point, and wow. It was 40F and it felt like I was slightly more than warm with sweat pants and a t shirt on, but not hot and sweaty. Very good. I wish it had ykk zippers though. These do tend to get caught a lot on the fabric.

Rated 5 out of 5 by from Ascent Sleeping bag. [This review was collected as part of a promotion.] I like the Ascent bag. It's light, packs down well. I haven't used it in mid-winter yet, but all of the zipper options are great during the spring and summer when temperatures vary a lot. So far, so good.

Rated 5 out of 5 by from Bag should last many uses!!! [This review was collected as part of a promotion.] Sleeping bag is very comfy! Have yet to sleep in the bag in cold temps, but I’m sure it will do great!
Date published: 2023-07-03
Rated 5 out of 5 by from Comfortable, lightweight and warm! [This review was collected as part of a promotion.] I camped with this during 50 degree weather and was toasty warm!! The material is nice, not like some sleeping bags where it isn't breathable and makes you clammy. I love this sleeping bag so far and look forward to testing it in much colder weather!
