{"product_id":"sea-to-summit-lightweight-compression-sack","title":"Sea to Summit Lightweight Compression Sack","description":"\u003cp class=\"product-lead\"\u003eThe Sea to Summit Lightweight Compression Sack is a packable gear organizer built for backpackers and camp travelers who need to reclaim space inside a pack. Made from bluesign-approved, RCS-certified recycled 70D nylon with a non-PFAS DWR finish, each sack compresses soft contents down to as little as one-third of their original volume. Available in 5L, 8L, 13L, and 35L capacities in Spicy Orange, Surf the Web, or Burnt Olive.\u003c\/p\u003e\n\n\u003ch2\u003eReclaim Space Without Sacrificing Durability\u003c\/h2\u003e\n\u003cp\u003eCompressing a sleeping bag, puffy jacket, or fleece layer to one-third its unpacked volume means the difference between a pack that closes cleanly and one that doesn't close at all. The Lightweight Compression Sack achieves that reduction through a set of nylon webbing compression straps that cinch evenly around the cylindrical body, eliminating the bulging that off-axis straps cause. The 5L and 8L each include two ladderlock straps and one side-release buckle strap; the 13L includes two ladderlock straps and two side-release buckle straps for additional control over larger loads.\u003c\/p\u003e\n\n\u003ch2\u003eRecycled Fabric, No PFAS Chemistry\u003c\/h2\u003e\n\u003cp\u003eThe main body fabric is 100% recycled 70D nylon, bluesign approved and RCS certified, treated with a C0 non-PFAS DWR finish that sheds light moisture without the persistent fluorinated compounds found in older DWR treatments. The inner face carries a PU coating and is finished in bright white, making it easier to spot gear inside the sack in low light. Buckles are 100% POM; webbing is 100% polypropylene.\u003c\/p\u003e\n\n\u003ch2\u003eDetails That Speed Up Camp Routines\u003c\/h2\u003e\n\u003cp\u003eAn attached flip-top lid keeps compression straps from tangling during packing and unpacking, a useful feature when hands are cold or light is fading. A nylon webbing handle on the round base gives a secure grab point when pulling the sack from a pack or stuff sack pile. The sack is water resistant, not waterproof: the seams are not tape-sealed and the opening does not use a roll-top closure, so it is not suitable as a dry bag in rain or water crossings.\u003c\/p\u003e\n\n\u003ch2\u003eFeatures\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCompression to one-third volume:\u003c\/strong\u003e ultralight nylon webbing straps cinch soft contents down by as much as two-thirds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRecycled 70D nylon body:\u003c\/strong\u003e bluesign-approved, RCS-certified fabric with non-PFAS DWR finish\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePU-coated interior:\u003c\/strong\u003e waterproof inner coating with bright white finish for easy gear visibility\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAttached flip-top lid:\u003c\/strong\u003e keeps compression straps organized and tangle-free\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNylon webbing base handle:\u003c\/strong\u003e secure grab point on the round base\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSize-specific strap sets:\u003c\/strong\u003e 5L\/8L use two ladderlock plus one side-release strap; 13L uses two ladderlock plus two side-release straps\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003ctable\u003e\n  \u003cthead\u003e\n    \u003ctr\u003e\n      \u003cth\u003eSize\u003c\/th\u003e\n      \u003cth\u003eProduct Weight\u003c\/th\u003e\n      \u003cth\u003ePacked Dimensions\u003c\/th\u003e\n      \u003cth\u003eColors Available\u003c\/th\u003e\n    \u003c\/tr\u003e\n  \u003c\/thead\u003e\n  \u003ctbody\u003e\n    \u003ctr\u003e\n      \u003ctd\u003e5L\u003c\/td\u003e\n      \u003ctd\u003e68 g \/ 2.4 oz\u003c\/td\u003e\n      \u003ctd\u003e15.2 × 15.2 × 29.6 cm (6.0 × 6.0 × 11.7 in)\u003c\/td\u003e\n      \u003ctd\u003eSpicy Orange, Surf the Web\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003e8L\u003c\/td\u003e\n      \u003ctd\u003e86 g \/ 3.0 oz\u003c\/td\u003e\n      \u003ctd\u003e18.1 × 18.1 × 35.5 cm (7.1 × 7.1 × 14.0 in)\u003c\/td\u003e\n      \u003ctd\u003eSpicy Orange, Surf the Web\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003e13L\u003c\/td\u003e\n      \u003ctd\u003e112 g \/ 4.0 oz\u003c\/td\u003e\n      \u003ctd\u003e20.5 × 20.5 × 43.3 cm (8.1 × 8.1 × 17.0 in)\u003c\/td\u003e\n      \u003ctd\u003eSpicy Orange, Surf the Web\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003e35L\u003c\/td\u003e\n      \u003ctd\u003e167 g \/ 5.9 oz\u003c\/td\u003e\n      \u003ctd\u003e28.8 × 28.8 × 57.8 cm (11.3 × 11.3 × 22.8 in)\u003c\/td\u003e\n      \u003ctd\u003eBurnt Olive, Surf the Web\u003c\/td\u003e\n    \u003c\/tr\u003e\n  \u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ctable\u003e\n  \u003cthead\u003e\n    \u003ctr\u003e\n      \u003cth\u003eSpecification\u003c\/th\u003e\n      \u003cth\u003eDetail\u003c\/th\u003e\n    \u003c\/tr\u003e\n  \u003c\/thead\u003e\n  \u003ctbody\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eMain body material\u003c\/td\u003e\n      \u003ctd\u003e100% recycled 70D nylon, bluesign approved, RCS certified\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eBuckles\u003c\/td\u003e\n      \u003ctd\u003e100% POM\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eWebbing\u003c\/td\u003e\n      \u003ctd\u003e100% polypropylene\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eDWR finish\u003c\/td\u003e\n      \u003ctd\u003eC0 non-PFAS\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eWater resistance\u003c\/td\u003e\n      \u003ctd\u003eWater resistant (not waterproof; seams not tape-sealed)\u003c\/td\u003e\n    \u003c\/tr\u003e\n  \u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003ch2\u003eWho This Is For and Isn't\u003c\/h2\u003e\n\u003cp class=\"product-fit-yes\"\u003eThe Sea to Summit Lightweight Compression Sack suits backpackers, overlanders, and car campers who need to compress sleeping bags, insulating layers, or other compressible soft goods to free up pack volume.

The seams are not tape-sealed and the opening does not use a roll-top closure, so water can enter if the sack is exposed to sustained rain or submerged.

However, tent canopy fabric does not compress as readily as down or synthetic insulation, so the full two-thirds volume reduction may not be achievable with a tent canopy inside.\u003c\/p\u003e\n\u003ch3 class=\"product-faq-q\"\u003eWhat is the Lightweight Compression Sack made from?\u003c\/h3\u003e\n\u003cp class=\"product-faq-a\"\u003eThe main body of the Sea to Summit Lightweight Compression Sack is 100% recycled 70D nylon, bluesign approved and RCS certified, with a C0 non-PFAS DWR finish on the outer face and a PU coating on the inner face.
