A clear TPU version of the fully welded Stopper dry bags, so you can see the contents of the bag from every angle. Durable, water shedding and abrasion resistant. The clean profile and oval base resists rolling and allows for easy packing. We used the best quality TPU, which is UV resistant and won't crack in extreme cold. A vertical stripe of color has been on printed on the bags with liter size for easy ID. The waterproof TPU roll top closure does not wick moisture. Features the patent pending Field Repair Buckle with stainless steel pins.
