I have the MH Phantom 15 LG. I love this bag. Weighs less than 2 lb., but is very warm. The zipper is a little sticky, but that is the price for LW. It would need a big fatty zipper and a bunch of extra cordura sewn in to make it snag proof. I can live with the compromise. It packs down really small. I'm 6'2", 180 lb. and I find it roomy enough. I used to use a Marmot reg. size and felt cramped all night. It is very well made, and higher quality than BA. I was torn between this bag and the Marmot Helium, but settled on this one because it was about $100 cheaper.
