Columbia Sportswear Unisex Adult River Runner XL Drypack Backpack - Waterproof Hiking Backpack for Outdoor Adventures, Camping & Travel Gear

Go big or go home. At 55 liters of carrying capacity, this celebrated wet-stopping backpack is officially super-sized. We’ve improved the River Runner’s roll-top closure—which now easily zips, rolls, and clips to the top. We also added rust-proof Vislon zippers for all you saltwater enthusiasts, a beefy neoprene hauling handle at back neck for extra-heavy loads, and a removable waist belt that keeps things secure during two-wheeled commutes. The foam padded back delivers great comfort and support, and the vented shoulder straps keep things comfortable when carrying a load. A waterproof front pocket keeps touchy items like cell phones and mp3 players safe and secure. The sternum strap has a built-in whistle, should you need to alert your team to something urgent.
