Ultralitesacks manufactures premium Dyneema products by hand in their Brookings Oregon workshop.
Dyneema material is 15x stronger than steel and has a very high tear resistance strength at a much lighter weight than any other material on the market.
These convenient roll top bags are the perfect way to keep organized without adding additional ounces to your pack. This bag is sewn and seam taped to make it essentially 100% waterproof.
Use the smaller sizes for hygiene products, electronics (battery bank, cords, camera gear), headlights, etc. The larger sizes will fit sleeping bags, clothes, or anything else you want to keep organized and dry!
