Offering serious adaptability for three-season camping, the Never Winter Sleeping Bag is back with upgrades big and small. This sleeping bag now features 650-fill hydrophobic down for an added touch of water resistance. Dual side zippers make getting in and out of the bag easier, and unzipping both sides transforms the snug mummy shape into a roomy bag with a blanket-like top. A zipper at the foot box can also be unzipped for extra space and ventilation, but it stays snug and doesn't let cool air slip in on chilly nights. And, our favorite update, both the rugged ripstop shell and soft taffeta lining are made from 100% recycled nylon.

Don't love the double zip
[This review was collected as part of a promotion.] Warm bag that packs down well and is light weight. But I don't love the top double zip. My feet would get hot and there was no way to vent because I could only open up the top part of the bag. Other bags with a full zip, I can either open up a vent hole for the feet, or unzip the whole bag and use it more like a blanket. Although I didn't end up using, I like the interior phone/watch/headlamp pocket.

Great Bag with a Retro Vibe
[This review was collected as part of a promotion.] Very warm and compact sleeping bag. The zippered toe box should come in handy for warmer nights in the woods.

Super warm!

Lofts up very well, it's super roomy and warm. I should've noticed this when I ordered it but the bag doesn't zip all the way but stops halfway. It's kinda difficult to get into the bag but not a problem!

First bag, comfy, well designed, perfect fit.
[This review was collected as part of a promotion.] I luckily bought the long model even though the normal one is for up to 6'. Very glad I did that. As my first sleeping bag, I got advice from so many people. Some told me to adhere to the temp rating, some said get a lower rating and just sleep on top of it if it's hot. I should have listened to my more experienced friend about sleeping on top. Temps dropped to 40 and I wish I got a bag that was rated even 20 or below. I was wearing just a t-shirt and running pants to sleep and everyone said I ought to just wear more to bed, but I like being less restricted when sleeping. The bag was just enough but would have liked to be a bit warmer. I ended up wearing running pants and a merino base layer to sleep for 50 degrees and it was fine. The material was nice, soft, and light. I appreciated the zips a lot but didn't get to try the split zip at my legs. Highly recommend for the quality!

Nice bag
[This review was collected as part of a promotion.] The only reasons I chose a 4 instead of a 5 are mainly because he hasn't tried it yet. I'm sure it's amazing, but there's always room for improvement. Which leads me to the second point, the colors. We just aren't people who appreciate noisy things. Muted solid colors are our favorite. So this is a little loud for us. But that has zero to do with quality, so overall we're thrilled.

Is this, or any of your sleeping bags, treated with DWR? If so, does the DWR contain PFAS, PFOS's, aka "forever chemicals"?
