  • Mummy shape (wider width) with #5 YKK two-way, separating zipper with locking sliders
  • Full draft collar provides an extra cushion of down around your neck to trap the heat
  • Trapezoidal footbox allows your feet to fall in a natural pose without compressing the sides
  • Continuous baffles let you position the insulation where you need it
  • 3D contoured hood opens wide for warm nights and cinches tight when the temps start to drop
  • Generous draft tube prevents cold air from seeping past the zipper
  • Overlapping dual-webbing zip guard guides the fabric away from the zipper and eliminates the need for a stiff or heavy fabric layer that can interfere with the draft tube seal
  • Includes storage bag & stuff sack


Mummy Sleeping Bags

Just Replaced Western Mountaineering

Just spent five nights in Central Idaho using this bag. Temps were getting down to zero and I was impressed with how warm I stayed. I added on some layers in order to stay warm but I'm certain I would have been equally or more cold with my WM 5 degree bag. The zipper and weight savings are both upgrades from my WM bag. The only complaint is the FF fabric doesn't hold up well against hot stoves - lol.

Three Season Comfort

Oddly enough I hadn’t seen many reviews for this bag online. It met the exact specs for size and fill volume that I was looking for. So, based on the specs I bought the raven and couldn’t be happier. It is such a comfortable bag. The huge baffles fill up all the small spaces wrapping my body like a cloud. The side baffles do their job to hold in heat even when I toss and turn. After long and consecutive 20 mile days in the wilderness my body would ache with pain. I was happy to never have a poor nights sleep and I owe it to the raven. I’m 6’ 175lb and purchased the 6’-6”. Could have gone either way on the 6’ length bag to save some weight. It has a lot of volume for down jackets and extra clothing. I am a warm/hot active sleeper and the bag was downright hot in the 40s paired with an X-therm mattress. This was easily remedied by using it like a quilt. Another option for warm temps would be to use an non insulated pad. Once I found the 30 deg temps the bag found it’s sweet spot. Even in the 30s I still needed to dump a small amount of extra warmth out of the foot box zipper. It is so warm and comfortable it is amazing. I have yet to spend much time moving down around the baffles but the versatility of the bag is definitely there for warmer nights. I will be using this bag to zero degrees with confidence. The raven is replacing a WM Alpenlite 20 bag for similar sizing, more down, and virtual no weight penalty. Thanks FF! Great bag!

Sleeping on a Cloud

Literally feels like a warm, soft, cloud over you that is warm without being hot, silky without being slippery, ultra comfortable and awesome. Absolutely love it. Will be buying more feathered friends products. Well worth the money. Wish I would have known about them sooner. Will never go back to less expensive bags again.

Awesome bag!!

This bag is incredibly light weight! It is very warm and will be a great asset in the mountains. I would highly recommend this product to anyone.
