Usage

Internal Storage External Storage Rugged Storage About The Product Lash to kayaks, bikes and 4WDs with conﬁdence, or add a Dry Bag Sling (sold separately, 2023 model or newer, sizes 5L – 35L only) for comfortable hands-free carrying.

Big River Dry Bags are a durable and abrasion resistant option that uses a strong 420D nylon fabric.

If your idea of outdoor recreation involves rugged water sports like kayaking, canoeing, rafting, or motorcycle touring, they are the perfect storage bags to keep your gear dry.

A white interior laminate affords greater visibility, and lash loops allow secure stacking or attachment to watercraft, motorcycles and other equipment.

The hypalon non-wicking roll-top closure keeps water out, and the Field Repair Buckles can be replaced in seconds with just a Philips screwdriver.

It also was designed with an oval base to save space when packing and prevent it from rolling away.

FAQs

Is this dry bag waterproof?

The body of the dry bag is waterproof (10,000 mm hydrostatic head). However, avoid submersion since water can seep through the roll-top closure of any dry bag.
