DESCRIPTION

Collapsible water reservoir for use as a lightweight water carrier or a replacement water bladder -- holds a 40 ouncer straight up! Lightweight, puncture-resistant 3-ply plastic laminate is lined with food-grade polyethylene that won't flavor your water with a plastic taste. Durable welded construction lets you boil, freeze, inflate, or collapse the bag over and over again. Comes with a screw-on closure cap--drinking tube assembly not included.
