Great concept/great bag - Sierra Designs Cloud 800 Dridown 20 Degree Sleeping Bags - Men's

I was looking for a 20 degree, light weight bag for backpacking and the Cloud 800 fit the bill. The zipper-less design allows me snuggle up when I need to and vent in the middle of the night when I'm restless. I also appreciate the trapdoor in the foot box because it always seems that no matter how cold it gets in the local SoCal mountains or the Rockies, my feet always end up too warm. The sleeping pad lock is a great improvement too. I love the idea of using an elegant, cutting edge design. Kudos for light weight, ease of use, warmth and design! I highly recommend this bag!
