Why We Like The Ascent 1100 Sleeping Bag

A wider mummy shape lets us spread out without sacrificing heat, rugged Pertex Quantum keeps cold and windy weather at bay, and lofty duck down ensures heat in the most frigid conditions.

I love my new sleeping

I love my new sleeping bag. I took it out on a camping trip at -1 °C and was warm all night. You have to know I am a very cold sleeper. The second time I took it out was a Bothy Trip. Inside the Bothy were maybe around 10 °C and I was very cosy and warm. When it got too warm I just put my arms outside and it was perfect. I am curious if it will keep me warm at -10 °C as well but that test has yet to be made. I did try the Alpkit Pipedream 600 and tested it at about +5 °C and it definitely wasn't warm enough for me. I tried it because it is much lighter and smaller in pack size than the Rab Sleeping Bags. But the Rab one was just much warmer for me and it really isn't that heavy when you compare it to my old Synthetic Mamut winter bag. All in all 5 stars! I'm looking forward to many more winter camping nights with my new sleeping bag:)
