Whoo-Hoo what a bag...!!!
I've had my Western Mountaineering bag for three years. It is just as warm now as it was the first time I used it. It has had a rough life, two thru-hikes on the Appalachian trail and survived the Colorado trail. It has spent half of it's life smashed in the bottom on a backpack, but it still retains all of its loft..!!The only down side is the half zipper. I understand it is necessray for the crazy light weight of this bag, but on warmer nights it stops you from opening up the bag and using it as a quilt.Over all a top of the line bag. I would not hesitate to buy another, if this one ever wears out...!!!!
