The Aquapac AQUA-760 15 Liter Noatak Dry Bag (Urban Grey) is a 100% waterproof combination dry bag, sling bag and daypack. It is made from ripstop nylon which is a woven fabric that has an extra thread added to the weave which stops a tear or rip from traveling across or down the fabric. The fabric is polyurethane (PU) coated to keep water out. There are two internal pockets to keep wet stuff and dry stuff separate inside the same bag.
The Noatak bag has a roll-seal closure that forms a simple carry handle and straps can turn it into a daypack/backpack. There are compression straps to make a smaller bag. Use a single strap to make a sling bag or attach it to a bike, boat or kayak using the reinforced attachment patch and compression straps.
