Got my underquilt today and I am really impressed. I talked to Adam a couple of times and what a nice guy. He rushed me my order as I was going to take my nephew to Linville Gorge this week but unfortunatly the post office got it here a day late and he can't go now. Oh well I will look for some group hangs coming up and get out there and try it out. It is the 20 degree phoenix with 2 oz overstuff. The loft of this thing is crazy. Just wanted to take the time to say thank you for the awesomeness.
