This has an air bladder support over the entrance and a vestibule that is very nice. Very good condition (or even better). No problems that I know of, no tears or stains.
Original bladder is fine, and there is a spare bladder. Has a unique air pump for the support bladder that requires practically no time or effort.

Width; from 26" at foot to 40" at entrance
Height; 26"
Bivy tent alone 2 lb
Bivy tent, accessories, bag 2.5 lb

I'm wanting $175, shipping included to Continental US
