{"product_id":"sea-to-summit-ultra-sil-nylon-stuff-sack-set","title":"Sea to Summit Ultra-Sil Nylon Stuff Sack Set","description":"\u003cp class=\"product-lead\"\u003eThe Sea to Summit Ultra-Sil Stuff Sack Set is an ultralight pack-organization system made from bluesign-approved Ultra-Sil 30D nylon with a C0 non-PFAS DWR finish and a 2000 mm hydrostatic head. Hypalon pull-tabs on the drawcord and throat make opening and closing fast even with gloved or wet hands. Two size sets are available: a 3\/5\/8L set weighing 76 g and a 5\/8\/13L set weighing 100 g.\u003c\/p\u003e\n\n\u003ch2\u003eUltralight Without Sacrificing Durability\u003c\/h2\u003e\n\u003cp\u003eUltra-Sil 30D nylon uses CORDURA yarns to deliver tear resistance well above what standard ultralight fabrics offer at the same weight. Double-stitched and reinforced stress points at the drawcord throat and base handle extend the life of the sack through the repeated stuffing and pulling that pack organization demands. At 76 g for the three-sack 3\/5\/8L set and 100 g for the three-sack 5\/8\/13L set, the weight penalty for carrying a full set is negligible against the organizational benefit.\u003c\/p\u003e\n\n\u003ch2\u003eWater-Resistant Fabric Keeps Gear Dry in Light Conditions\u003c\/h2\u003e\n\u003cp\u003eThe C0 non-PFAS DWR finish on the outer face of the Ultra-Sil 30D nylon sheds light moisture and trail splash without relying on PFAS chemistry. The fabric's 2000 mm hydrostatic head adds a further margin against incidental water contact. These sacks are not waterproof (the seams are not tape-sealed and the top uses a drawcord rather than a roll-top closure), so gear that must stay completely dry in sustained rain or submersion needs a sealed dry bag instead.\u003c\/p\u003e\n\n\u003ch2\u003eSlippery Shell Makes Pack Loading Faster\u003c\/h2\u003e\n\u003cp\u003eThe siliconized Ultra-Sil fabric has a low-friction outer surface that lets each sack slide in and out of a pack's main compartment or pockets without snagging on other gear. A reinforced pull handle at the base gives a secure grip point for extracting a sack that's been buried under other kit, so there's no need to dig or unpack to reach a specific sack.\u003c\/p\u003e\n\n\u003ch2\u003eFeatures\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003ebluesign-approved Ultra-Sil 30D nylon:\u003c\/strong\u003e CORDURA-yarn construction with a 2000 mm hydrostatic head\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eC0 non-PFAS DWR finish:\u003c\/strong\u003e water-resistant outer face without PFAS chemistry\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHypalon pull-tabs:\u003c\/strong\u003e durable tabs on both the drawcord and the tear-proof throat for easy one-handed operation\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReinforced base pull handle:\u003c\/strong\u003e secure grip point for sliding sacks in and out of a loaded pack\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDouble-stitched stress points:\u003c\/strong\u003e reinforced at the throat and handle for long-term durability\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\u003eSpecification\u003c\/th\u003e\n      \u003cth\u003e3\/5\/8L Set\u003c\/th\u003e\n      \u003cth\u003e5\/8\/13L Set\u003c\/th\u003e\n    \u003c\/tr\u003e\n  \u003c\/thead\u003e\n  \u003ctbody\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eSack sizes included\u003c\/td\u003e\n      \u003ctd\u003e3 L, 5 L, 8 L\u003c\/td\u003e\n      \u003ctd\u003e5 L, 8 L, 13 L\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eWeight\u003c\/td\u003e\n      \u003ctd\u003e76 g \/ 2.7 oz\u003c\/td\u003e\n      \u003ctd\u003e100 g \/ 3.5 oz\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eMaterial\u003c\/td\u003e\n      \u003ctd colspan=\"2\"\u003e100% Nylon: Ultra-Sil 30D with CORDURA yarns, bluesign approved\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eDWR finish\u003c\/td\u003e\n      \u003ctd colspan=\"2\"\u003eC0 non-PFAS\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eHydrostatic head\u003c\/td\u003e\n      \u003ctd colspan=\"2\"\u003e2000 mm\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eSKU\u003c\/td\u003e\n      \u003ctd\u003eA4550\u003c\/td\u003e\n      \u003ctd\u003eA4551\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 Ultra-Sil Stuff Sack Set suits backpackers, overlanders, and frequent travelers who want a lightweight system for organizing clothing, electronics, or camp gear inside a pack or bag.
