Big Agnes - Women's Sidewinder SL 35°

I am a very dynamic sleeper, best bag I’ve used is the big Agnes sidewinder.

I have the SL35 and have used it for fall and spring in PA, no complaints. For winter or colder climates the SL20 would probably be more appropriate. I’m a cold sleeper though; I find sleep systems to be very subjective.

If you are a side sleeper check out big Agnes’s sidewinder or the torchlight- I am also a side sleeper and I like these two

Big Agnes Sidewinder is a good mummy for made specifically for side sleeping. I have the 20 deg F and it works great. Plenty of room even bundled up fully clothed with outer layers on. The zipper is on the front/top of the bag instead of on the side, which is great for moving with the bag and getting in and out of it. Everyone talks about quilts being the new craze but its definately a matter of preference, some love them, some hate them.

Yes I came to say I love my Big Agnes sidewinder! so much roomier for my legs and I love the zipper set up. I'm 5' 10" and the regular is plenty of room for me. I have the SL20 and have been comfy even when temps are hovering around freezing.

Quilts, semi rectangular bags (Sea to Summit Trek and Ascent Down) or the Big Agnes Sidewinder series are what you want. The Nemo Spoon series of down bags are also quite roomy. I sleep on my side. I use Hammock Gear Econ Borrows most of the time and I have a Marmot Col -20F bag for anything 20F and below.

I'm from Canada, so not sure the difference in availability. I've been mostly happy with the Big Agnes Sidewinder that I replaced my North Face Cats Meow with. My main complaint is that it doesn't compress as small as I'd like. It's been very cozy, and I sleep curled in a ball on my side. I do use a CoolMax liner inside. It is too warm above about 20deg celcius, but sleeping with it open was ok. Has been great down to -16celcius (caveat of I also had hand warmers in there with me, and was on a mattress in an RTT not backpacking in winter). I was trying to find a Gear Lab review, came across this one. It has some annoying ads: https://www.campman.com/blog/gear-review-big-agnes-sidewinder-sl-20-sleeping-bag/ And this comparison review of a few: https://www.outdoorgearlab.com/topics/camping-and-hiking/best-ultralight-sleeping-bag
