If it's a lightweight, compressible pack you're after, the Ultra Kompressor might be the solution you've been looking for. With its plentiful mesh side and front pockets, molded shoulder straps, removable back panel and three compression points, the Ultra Kompressor can hold a lot and pack it down to almost nothing. At less than a pound and a half you'd hardly notice this 20L pack at all, if you didn't come to love it so much.
