Just got my Stealth! (Review linked)
I used to take my JRB No Sniveler on most of my camping trips but it's pretty warm for summertime, and I was carrying an extra 5.25 oz of quilt that just made me sweat at night. So I bought the Stealth. I think it'll be just what I need for summer temps and it should save quite a bit of pack space as well. I started posting some thoughts on it on my page...I'll keep updating as I get more experience with it. It may turn it into a full review eventually.
