They can be rolled and squeezed into tight spaces and, with the use of 300D polyester for the exterior, they have a high abrasion resistance. A double layer tough Mylar bladder holds your water (or wine) safely and the unit can be easily operated with one hand. Note: The Pack Tap is not safe to use with hot water.
