The SealLine Discovery Waterproof Dry Bag is an ultra-durable, multipurpose dry bag. Made of PVC-free materials, the Discovery Dry Bag features an oval bottom that not only helps keep the bag from rolling around, it also makes packing it easier. The DrySeal roll-top closure is easy to use and ensures a tight, protective seal for use in demanding conditions. Its fully welded seams result in stronger and more durably waterproof construction compared to sewn-and-taped seams, making the Discovery Dry Bag ideal for anything from day floats, fishing, or kayaking to overland expeditions as a portage pack.
