After two years of development and a third year of testing, Watershed Drybags of Asheville, N.C., has released dry bags made of a new proprietary material, Kryptothane™ Plus.
The company started with a strong and resilient 840-denier nylon base fabric and employs an extrusion process on both sides using pigmented polyurethane. The resultant coating is thicker, with enhanced UV resistance. Through a specialized roller process, the material receives a grippy embossed texture.
Watershed Drybags’ products have double or triple layers of fabric at the seams, which are RF-welded together. The company’s waterproof products include survival-equipment bags, kayak bags, totes, backpacks, gun bags, and liners and dividers that turn two items in their product lines into waterproof camera bags. Some have an optional inflate/purge valve to allow the increase or decrease of air inside a bag for flotation. Watershed Drybags have been tested down to 300 feet underwater.
