Sea To Summit Big River 35L Dry Bag - Picante Red

Sea To Summit Big River 35L Dry Bag - Picante Red: Heavy-Duty 35-Litre Waterproof Storage for Kayaking, Bikepacking, and Overland Adventures

When your adventure puts your gear at serious risk of water, abrasion, and impact, the Sea to Summit Big River 35L Dry Bag in Picante Red is the heavy-duty storage solution built to take it. Constructed from abrasion-resistant 420D nylon laminated with TPU film and finished with a triple-coated base, the Big River is engineered for the demands of kayaking, canoeing, rafting, motorcycle touring, bikepacking, and 4WD overland travel — environments where a lightweight dry bag simply will not hold up. At 35 litres, it provides generous capacity for a full day or overnight kit including sleeping bag, clothing, and camp essentials, while the hypalon roll-top closure, multiple lash points, Field Repair Buckles, and white interior laminate combine to make it the most practical and repairable large-format dry bag available for South African water and adventure sports use.

Key Benefits:

* 420D TPU-Laminated Nylon Construction: Heavy-duty 420D nylon ripstop face fabric laminated with a TPU film provides the structural strength and waterproof barrier needed for rugged kayaking, rafting, and overland use — meaningfully tougher than the lighter nylon fabrics used in standard dry bags, with UV resistance for extended outdoor exposure on South African rivers, coastlines, and overland routes
* Triple-Coated Base for Abrasion Resistance: An additional triple-coat treatment on the base of the bag provides maximum protection at the highest wear point — the contact surface most likely to experience abrasion on kayak decks, rock ledges, vehicle loadbeds, and ground surfaces during loading and unloading across rough adventure terrain
* Hypalon Non-Wicking Roll-Top Closure: The hypalon roll-top seals out water without wicking moisture into the closure material itself — a critical durability advantage over standard nylon roll-tops that absorb and retain water over time, maintaining a reliable waterproof seal across repeated use in fully wet environments like surf launches, river crossings, and rain-soaked overland trips
* Multiple Lash Points with Double D-Rings: Integrated lash rails and double D-rings around the bag provide multiple secure attachment points for mounting to kayak deck lines, bicycle rack systems, motorcycle luggage frames, and 4WD roof racks or loadbeds — the 35L size is also compatible with the separately sold Sea to Summit Dry Bag Sling for hands-free backpack-style carrying
* Field Repair Buckles for Trailside Maintenance: Roll-top buckles are designed as Field Repair Buckles, replaceable in seconds with a standard Phillips screwdriver without requiring adhesives, specialist tools, or factory service — a practical design feature that extends the working life of the bag across years of hard adventure use in remote South African locations far from any retailer
* White Interior Laminate and Oval Base Design: A bright white interior laminate dramatically improves visibility when locating gear inside the bag in low-light conditions — on early morning river launches, inside vehicle storage, or in camp after dark — while the oval base prevents the bag from rolling away on sloped surfaces and optimises packing efficiency alongside other dry bags in kayak hatches or panniers

At 35 litres, the Big River occupies the XL position in the lineup — large enough to contain a sleeping bag, down jacket, full change of clothing, and camp layers with room to spare, yet compact enough when empty to roll down and stow as a dry bag reserve for expedition use. The non-PFC PU coating throughout is environmentally responsible and maintains full waterproof performance without PFAS chemicals — a commitment that runs across the entire Sea to Summit dry storage range. Whether you are launching off Gordon's Bay into the Cape's surf, running the Orange River through the Northern Cape, or lashing gear to a 4WD rack for a multi-day Richtersveld expedition, the Big River 35L in Picante Red gives you the waterproof storage confidence to focus entirely on the adventure ahead.
