Big Agnes - Sidewinder SL 20°

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.

If your biggest concern about a sleeping bag is room for your legs to move without feeling constricted, I would try out Nemo or Big Agnes sleeping bags. Both tend to have wider profiles. Definitely go for a bag that is rated at least 10 degrees lower - preferably lower - than the temps you expect to sleep in. Theres multiple problems with layering with clothing like this, one of which is not the warmth specific factor but the breathability. One or two layers is one thing, but with all the listed clothing and then something like the picture on top, you're going to build up humidity near your body you can't get rid of, and you'll become even colder. Next, a sleeping bag basically creates a warm pocket of air around you. The insulation in the bag helps create and maintain this pocket. The more compressed this insulation, the worse it performs. With layering clothing, you compress the insulation, making it less effective. On top of that, insulation is minimal if not nonexistent at the seams. Some puffy jackets and "extreme temp" clothing gets around this by minimizing seams but there's almost always a few somewhere, which means no air pockets and no warmth. If I could recommend the best case scenario for you, it would be this: find a sleeping bag you can tolerate rated to a temp appropriate for your conditions, 15F at a minimum, best scenario a 0F. Dress in only your smartwool layers, and make sure you have a good pad/sleep set up underneath you.

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

Seconding the Big Agnes down sleeping bag! I'm a side sleeper and finally invested in a BA Sidewinder after years of getting tangled up in my standard bag. More than worth the money.

We have one of these from Big Agnes. Works pretty well, although when my daughter got big enough, she could roll the whole mat over. I think it's this one: [https://www.youtube.com/watch?v=InhGM1Y2ksM](https://www.youtube.com/watch?v=InhGM1Y2ksM)

I went rei big Agnes, but I also have 2 (20 year old) down bags that I put inside each other that can keep me just as warm and combined they are as small and light as big Agnes but with down moisture is the enemy and in winter there is plenty so there is that

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.

Reputable brand. Will likely be expensive. For you 5°C you want a 0° or a -7° bag. In north America that would be a 30 or a 20 and I recommend a 20 Figure out synthetic vs down and side sleeper vs back sleeper. Watch a bunch of YouTube. Read articles.

I'm in Canada. My Big Agnes bag is still called sidewinder 20 😁 Over the years I've learned some understanding of freedom units

A Big Agnes sleeping bag with down that fit me correctly. I was iffy on the price at first, but it turns out I had basically used ill fitting, non insulated sleeping bags for years of wilderness camping. Getting a good nights sleep anywhere, especially away from home, makes a huge difference.

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.
