SEA TO SUMMIT Big River Dry Bag 20L

Description

Keep your gear safe, dry and adventure‑ready with the Big River Dry Bag 20 L from Sea to Summit. Built with rugged 420D nylon laminated with TPU film, this dry bag boasts a hydrostatic head of approximately 10,000 mm and features a non‑wicking Hypalon roll‑top closure to protect contents from inclement weather and spray. Designed for pack‑down performance with an oval base that prevents rolling and a white‑interior laminate for better visibility of packed gear, it includes multiple lash points and D‑rings for secure attachment to kayaks, bikes, motorcycles, 4WDs or sleds. Whether you’re bike‑packing, rafting, van‑life touring or simply need durable storage for your outdoor gear, the 20 L Big River Dry Bag delivers strength, functionality and smart design.
