Tyvek Tape is the packraft version of duct tape. It can repair everything from a pinhole to a packraft that has been shredded by a grizzly bear. Tyvek Tape has no stretch and its acrylic adhesive bonds extremely well to our boats (too well in fact - read the Field Repair Notes) so it can hold a large tear together even if you don't have Tenacious Tape backing. The only things it doesn't repair well are floors (due to their dimpled surface) and valves. Wrap it around your paddle shaft or water bottle when you head into the field. the mini roll is perfect for individual use.
