So I am a huge fan of Big Agnes and all they do--between me and my wife we now have 3 big agnes bags, one tent, one sleeping pad. Why do I like their stuff...quality and thoughtful design. The Kings Canyon is all that. I fidget a bit and I tend to get warm. I have a decent ultra light weight warm weather bag that has served me well but I have had enough of fumbling to get my temp right and feeling like I am sliding off my pad (I have been spoiled by my other BA bags with the sleeping pad sleeve). Enter Kings Canyon. It's pretty simple: light weight open design that you can easily tuck around you or open up to get your sleep temp just right. So pretty simple, pretty great. Simply put a quilt with that Big Agnes thoughtful design applied to it.
