I was checking out the Yeti at the Northern Hang and decided that a 3/4 under quilt would work good for me. I use a frameless pack with a piece of cc pad for support. The pad will work perfect under my feet slipped between the BB layers. I am a cold sleeper, so for now I'm considering this a three season quilt. Not quite sold on winter use. Some of these guys must have ice in their veins. I may use it with my HR UQ from JRB in really cold weather. Will work great for a layering system. It was smaller and lighter than a different one I was looking at which was also very nice. I am surprised that the Jacks don't offer a 3/4 length. I thought I read on a different post on their philosophy of using a full length as apposed to a 3/4, but I see it working great for a lot of people. So here I go, Yeti another quilt .
