It finally arrived.
I wish I could give a glowing report/lengthy review, but, it's too small and/or I'm too big.
Details: I'm 6'-0"/230#, and I can barely get in the bag. Think shrink wrapped. There is no footbox, as such, and the insulation was compressed there, and on top of my head. Girth is adequate, barely, but it's no bag for a claustrophobe. This was with the bag rolled out on a bed...in a hammock, it is simply undoable...I tried, and couldn't get 'er done.
On the plus side, this bag, @ <$50, is a good value for smaller pepes. And I'm totally diggin' the center zip...I don't know why all SBs aren't built that way.
Hope this helps anyone contemplating buying these (ICW/ECW) bags.
