Not as warm as I would have liked and the side zipper takes getting used to

Finally A Comfortable Sleeping Bag

Im a side sleeping and have struggled with mummy bags. This thing is incredibly comfortable and warm. I've got to use is a few times already and can't wait for the temps to drop.

A Great Choice For A Side Sleeper.

I have always twisted my bag around to keep the face opening correct. This bag works great for when I am on my side, and the pillow holder is a great addition. I wasn't sure how this would turn out, but it has worked out well for me. This is a good choice either starting out or upgrading from a lesser product. It is lightweight and packs down small, now that I am carrying a much smaller pack, this has been a good upgrade.

Totally A Side Sleeper

Love that I found a bag that lets me comfortably sleep on my side all night. Not necessarily a solution for everyone as my wife has pointed out it doesn't feel as comfortable when lying on your back. A great mid-range bag for someone looking to expand their options

Awesome Bag!!

I've used this bag for going on 6 months now and I couldn't be happier. I am predominantly a side sleeper and it works wonderfully. Super comfortable and it packs down really well. I've slept out in 20 degree weather and I was still comfortable (I sleep warm). I'm 6 2 and I have the long and I fit very well.

Calling All Side Sleepers

Great sleeping bag for side sleepers; not so great for those of us who roll around from belly to right side to back to…you get the point. My Sidewinder bag is extremely comfortable, warm & well made bag (albeit there are still some kinks with the zipper that BA needs to work through). Packs a little larger than I personally prefer for a down bag, but it's still good. Overall I like the bag, but it's just not going to be a go-to bag, so I ended up getting a Torchlight, which does allow me to roll around without feeling too restricted.

Comfortable

Comfortable for a side sleeper. If you have broad shoulders, go with the "long" size. You'll appreciate the extra space. Pillow Barn is handy.

Meh

I thought I would love this because I am a side sleeper. Unfortunately if you have to move or roll over or anything it sucks. Should have just bought a normal bag instead of the sidewinder.

Warm And Great Attention To Detail.

This sleeping bag has a silkier, smoother texture than I've ever seen before. Also, the no-snag zipper works great. Also, the side-sleeping orientation is amazing. It's warmer and my face isn't halfway in the hood all night. The weight is respectable for how warm it is.

I'm a side only sleeper and have been waiting for this bag my whole life... well, not the first 4-5 years of my life, but almost my whole life. Anyway, nice and light, really warm, feels great. I plan on getting a warm weather bag soon!

Great Bag For Side Sleeper

Nice and light, easy zip up, lived up to warmth rating, comfortable material

Perfect For Side Sleepers

Pleasant experience with the product. Comfort rating was on point, the design for side sleepers works well. Colors are nice. Everything is well made

Best Bag Ever

I'm a bigger guy and the sidewinder fits me perfect. I got the best night sleep on a 30 degree night with the sack. It's warm, comfortable, and pack perfect in the backpack.

Near Perfection

I wanted to give this bag 5 and 10 but the fact is I prefer a flat sleeping position and not having my head fixed in a small area, or having to use a small camping pillow. As a side sleeper it performed as described and I used this out in the field sleeping under the stars for 5 nights in temps from low 50s to high 50s. I had no issues staying warm in the bare min. clothing and no extra gear needed.

Great Sleep

This is the most comfortable bag I've ever owned, especially as a side sleeper!
