Known for creating high-end phone cases and coolers, OtterBox's newest venture is the OtterBox Yampa Series -- a line of waterproof duffle bags that come in three sizes, including 35-liter, 70-liter and 105-liter styles.
Each bag from the collection is made from a TPU-coated nylon material that offers waterproof protection as well as UV, puncture and chemical protection. The open-celled foam interior protects all contents from dropping and all types of weather to keep valuables safe at all times. Although the bag is packed full of features and protective elements it is still lightweight and easy to carry on long trips for camping, rafting or hiking.
Every style from the OtterBox Yampa Series has back straps, allowing versatility when it comes to carrying the pieces as either a duffle bag or backpack.
