Sea To Summit EVAC 65L Dry Sack - Blue

Sea To Summit EVAC 65L Dry Sack - Blue: Lightweight Valve-Free Compression Dry Sack for Full Pack Liners and Expedition Gear Organisation

The Sea to Summit EVAC 65L Dry Sack in Blue is the largest format in the EVAC range — purpose-built as a full pack liner for 50 to 65-litre rucksacks, a complete overnight gear organiser, or a consolidated waterproof compression sack for an entire multi-day kit. At 65 litres, the same bluesign-approved recycled 70D nylon waterproof body and eVent air-permeable waterproof base that define the EVAC system work at expedition scale — providing genuine valve-free compression across a full load of sleeping bag, insulation, and clothing simultaneously, while maintaining 10,000mm hydrostatic head waterproofing throughout. For South African backpackers, paddlers, and overlanders who want to waterproof and compress their entire kit in a single sack that doubles as a pack liner, the EVAC 65L in Blue is the most comprehensive dry compression solution in the Sea to Summit range.

Key Benefits:

* Full Pack Liner at 65-Litre Scale: At 65 litres the EVAC sack functions as a complete internal pack liner for 50 to 65-litre rucksacks — eliminating the need for a separate rain cover by waterproofing the entire pack contents from the inside, a more reliable approach in South African mountain weather where wind-driven rain bypasses external covers and pack seams remain the primary water ingress point
* eVent Air-Permeable Waterproof Base: The 70D eVent fabric base allows air to pass freely outward when the sack is compressed, while preventing water from entering in the opposite direction — at 65 litres, this valve-free compression capability consolidates a full overnight kit including sleeping bag, insulation layers, and clothing into a meaningfully reduced packed volume without straps, valves, or mechanical components to manage or fail
* Valve-Free Compression Without Straps: Pack your complete compressible kit, roll the hypalon closure down, and sit on or firmly press the sack to push air out through the eVent base — the 65L volume accommodates an entire multi-day kit for overnight routes in the Drakensberg, Cedarberg, and Cape mountain ranges, or a complete kayak expedition sleep and clothing system in a single waterproof, compressed package
* Bluesign-Approved Recycled 70D Nylon Body: The main body fabric is both recycled and bluesign-approved — meeting independent certification standards for responsible material sourcing and ethical production — with a C0 non-PFC DWR finish across both the body and eVent base fabrics, maintaining full waterproof performance without PFAS chemicals across the full working life of the sack on South African trails, rivers, and overland routes
* Hypalon Non-Wicking Roll-Top with Field Repair Buckle: The hypalon roll-top closure maintains a reliable waterproof seal at the closure point without wicking moisture into the sealing material, and is secured with Sea to Summit's patented Field Repair Buckle replaceable in seconds with a standard Phillips screwdriver — a practical field-serviceability feature that becomes particularly valuable on multi-week expeditions far from any gear retailer
* Double-Stitched and Tape-Sealed Seams with White Interior Coating: All seams are double-stitched and fully tape-sealed for waterproof integrity across the complete 65-litre sack body — not limited to the closure — ensuring the 10,000mm hydrostatic head rating is maintained throughout, while the white interior coating provides maximum contrast for gear visibility when locating specific items inside the sack in low-light camp conditions

The EVAC 65L in Blue represents the complete-system application of the EVAC technology — rather than organising individual gear categories into separate sacks, the 65L consolidates an entire kit into a single waterproof and compressed unit that slides into a pack, sits inside a kayak hatch, or stows in a vehicle storage bay. The Blue colourway provides clear visual identification alongside other EVAC sizes and Big River dry bags in a mixed dry storage system. Pro tip from Sea to Summit: after compressing the air out through the eVent base, immediately close the sack inside your pack so it cannot draw air back in through the base — pack the 65L into the bottom of your rucksack as a fully waterproofed liner and build the rest of your kit around it for a clean, protected load on every South African adventure.
