Sea To Summit Lightweight 35L Dry Bag - Surf the Web

Sea To Summit Lightweight 35L Dry Bag - Surf the Web: Versatile Waterproof Dry Bag for Overnight Gear, Pack Liners, and Large-Volume Adventure Organisation

The Sea to Summit Lightweight 35L Dry Bag in Surf the Web is the largest format in the Lightweight range — purpose-sized as a pack liner for 30-litre-plus rucksacks, a complete overnight gear organiser, or a consolidated large-volume waterproof sack for multi-day clothing, sleeping systems, and soft kit. Built from bluesign-approved recycled 70D nylon with a C0 non-PFC DWR finish and a white polyurethane interior coating rated to 10,000mm hydrostatic head, the Lightweight 35L delivers reliable waterproof performance in a soft, pliable, and lightweight format with a hypalon non-wicking roll-top closure, D-ring attachment point, and oval base. The vivid Surf the Web colourway makes colour-coded pack organisation instant and intuitive — at 35 litres it bridges the gap between a dedicated clothing sack and a full pack liner, keeping an entire overnight soft kit dry and easy to locate through the white interior coating across South Africa's most demanding trail and travel conditions.

Key Benefits:

* Bluesign-Approved Recycled 70D Nylon with 10,000mm Rating: The main body fabric is both recycled and bluesign-approved — meeting independent ethical sourcing and production certification standards — with a C0 non-PFC DWR finish on the exterior and a white polyurethane interior coating rated to 10,000mm hydrostatic head, delivering strong waterproof performance in a large-format bag that remains soft, pliable, and packable enough for internal use as a pack liner or consolidated gear sack across backpacking, cycle touring, and overlanding applications
* White Interior Coating for Gear Visibility: The bright white polyurethane interior coating creates maximum contrast against dark clothing and soft gear inside the bag — dramatically improving visibility when locating specific items in low-light conditions at dawn starts, evening camp setups in poor weather, and night packing after a long day on South African trails, river banks, and coastal campsites where a head torch is the only available light
* Hypalon Non-Wicking Roll-Top Closure: The hypalon roll-top seals out water without wicking moisture into the closure material itself — a meaningful advantage over webbing-closure alternatives that absorb and retain water — maintaining a reliable waterproof seal across sustained rain, river crossings, condensation-heavy mountain conditions, and wet coastal environments along the Cape, Garden Route, and KwaZulu-Natal coastlines across repeated multi-day use
* D-Ring Attachment Point at Buckle: A built-in D-ring at the roll-top buckle provides a direct attachment point for a carry strap, karabiner, or lanyard — allowing the 35L Lightweight to be clipped to pack exterior loops, bicycle rack systems, kayak deck lines, and vehicle attachment points, adding versatile mounting options beyond simple internal pack storage for South African adventures spanning water, trail, and overland formats
* Oval Base for Pack-Contour Integration: The oval base profile fits cleanly into the contoured internal spaces of large backpacks, expedition duffels, and travel bags without the dead space created by round-base sacks — and prevents the loaded bag from rolling away on sloped surfaces at camp, on boat decks, in vehicle storage bays, and on the sloped ground of South African mountain campsites during loading and unloading
* Colour-Coded Pack Organisation in Surf the Web: The vivid Surf the Web blue colourway enables intuitive colour-coded dry bag organisation inside a pack or kit system — the 35L is identified and retrieved at a glance alongside smaller Lightweight sacks assigned to different gear categories, a practical pack management system for multi-day routes where fast camp transitions and clear gear separation save time and reduce frustration

At 35 litres the Lightweight sack functions as a complete overnight gear organiser — sleeping bag, insulation layers, and full clothing system in a single consolidated waterproof package — or as an internal pack liner for a 30 to 40-litre rucksack that waterproofs the entire pack contents from the inside without a separate rain cover. It also covers large clothing loads for extended travel trips, tent and shelter systems, and bulky soft kit categories that overflow the smaller Lightweight formats. As a recycled fabric product with non-PFC DWR chemistry throughout, it reflects Sea to Summit's commitment to responsible material sourcing. Suitable for general paddle and coastal splash-resistant use but not recommended for full submersion or dedicated water sports — the Big River range covers demanding water sports applications.
