I've always been a fan of BA Bags. I've owned a Lost Ranger, Storm King, Buffalo Park and a Mystic SL. Their bags definately improve with increased $$$. Some will say their temp ratings are a little off. I like slipping my pad into the bag as I can sometimes have a hard time staying on a pad. Overall, I am a fan of BA bags but there are a ton of bags out there to choose from. Some of my other favorites are Western Mountaineering, Mountain Hardware and the new KUIU Bags intrique me. Gonna be in the market for a new 0 degree bag and not sure what way I will go...
