HydroGuard’s money-saving combo pack includes a 10L, 20L and 30L dry bag so you’ll have the right size water-resistant dry bag for any outdoor activity. Protect cellphones, cameras, clothing, and other necessities while you and your family enjoy camping, swimming, fishing, or mountain biking or other vacation spot where water, dirt or mud can be a hazard to valuable gear. All three bags are rated at IPX6 and will protect items from a 12.5mm spray of water (100l/min) in any direction for at least three minutes. Designed to fit comfortably on both men and woman, these HydroGuard Water-resistant Combo Pack Dry Bags are made of a proprietary blend of polyester and waterproof coating material that helps keep items dry without adding much weight to the load.
