Know before you buy
No, the Big River Dry Bag is designed for non-submersible use. While it features a highly water-resistant roll-top closure and sealed seams, it is intended to protect gear from splashes, rain, and brief exposure to water rather than prolonged underwater submersion.
Yes, the interior of the bag is finished in white. This high-contrast lining makes it significantly easier to locate smaller items or gear tucked at the bottom compared to bags with dark interiors.
The bag is equipped with Field Repair Buckles that feature stainless steel pins. You can easily replace a broken buckle on the go using only a Phillips screwdriver, so you don't have to worry about your gear being compromised during a trip.
The bag features an oval-shaped base, which is specifically designed to resist rolling. This shape provides a more stable footprint than traditional round-bottom dry bags, helping it stay put on uneven surfaces.
The bag includes multiple lash points integrated into the design. These allow you to securely strap the bag to a kayak deck, a canoe thwart, or the exterior of a larger backpack for versatile transport.
Yes, the bag is constructed from 420D Nylon with a triple-coated base. This combination provides excellent abrasion resistance, making it a reliable choice for demanding environments where the bag might rub against rocks or rough gear.
