SEA TO SUMMIT Big River Dry Bag 8L

Description

The Sea to Summit Big River Dry Bag 8 L is a durable, waterproof storage solution engineered for serious outdoor adventures. Built with abrasion‑resistant 420D nylon laminated with a TPU film and featuring a triple‑coated oval base, this bag offers high durability and water protection during kayaking, bike touring, overlanding, or any gear‑intensive outing. Lightweight yet tough, the 8‑litre size strikes a perfect balance between compact packing and essential volume, making it ideal for day trips, medium‑length excursions and as a dry‑gear organiser. With lash points, an oval base to prevent rolling, and a white interior for visibility of gear, it’s designed for the demands of on‑ and off‑water adventurers. 


Key Features

  • Ultra‑Tough 420D Nylon with TPU Laminate – Provides a hydrostatic head of 10,000 mm and excellent resistance to abrasion & puncture. 

  • Hypalon Non‑Wicking Roll‑Top Closure – Ensures effective water‑sealing without wicking moisture into the bag. 

  • Triple‑Coated Oval Base – Boosts abrasion resistance and prevents the bag from rolling away when situated on uneven surfaces. 

  • Multiple Lash Points & Grab Handles – Secure attachment to kayaks, bikes, roof racks or 4WDs—plus low‑profile handles for easy carrying. 

  • White Interior Laminate – Enhances internal visibility so you can locate gear quickly, even in low light. 

  • Day‑Trip Perfect Volume – The 8 L capacity offers a compact size that still accommodates essentials like dry clothes, electronics, food or safety gear.
