Where the Ultra-Sil version chases minimum weight, this one is cut from 210D PU-coated nylon and built to take abuse in a duffel, a truck bed or a canoe. Four evenly spaced straps pull a 15 liter load down to roughly 5 liters without letting the sack bulge, and the \"Flip-Top-Lid\" design keeps the straps from tangling every time you open it.\u003c\/p\u003e\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\"Flip-Top-Lid\" design prevents strap tangling\u003c\/li\u003e\n\u003cli\u003eMade of heavy-duty 210D PU-coated nylon\u003c\/li\u003e\n\u003cli\u003eFour straps for even compression; eliminates bulging\u003c\/li\u003e\n\u003cli\u003eExtra-long straps so the sack is easy to fill to maximum capacity\u003c\/li\u003e\n\u003cli\u003eNylon webbing pull handle on the bottom\u003c\/li\u003e\n\u003cli\u003eBlack body with end panels in blue, red, yellow, black or green\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003ctable\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth\u003eModel\u003c\/th\u003e\n\u003ctd\u003eCompression Sack – M (Medium)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eSKU\u003c\/th\u003e\n\u003ctd\u003estscompsackm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eSize\u003c\/th\u003e\n\u003ctd\u003e8\" x 18\"\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eVolume (max \/ compressed)\u003c\/th\u003e\n\u003ctd\u003e15 L \/ 5 L\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eFabric\u003c\/th\u003e\n\u003ctd\u003e210D PU-coated nylon\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eCompression\u003c\/th\u003e\n\u003ctd\u003e4 straps with flip-top lid\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eHandle\u003c\/th\u003e\n\u003ctd\u003eNylon webbing pull handle on base\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n\u003ch3\u003eHow much does the Sea to Summit Compression Sack M compress?\u003c\/h3\u003e\n\u003cp\u003eThe Sea to Summit Compression Sack M (stscompsackm) takes a 15 liter load down to roughly 5 liters once all four straps are cinched — about a two-thirds reduction. It measures 8\" x 18\" uncompressed.\u003c\/p\u003e\n\u003ch3\u003eWhat is the Sea to Summit Compression Sack M made of?\u003c\/h3\u003e\n\u003cp\u003eThe Sea to Summit Compression Sack M (stscompsackm) uses heavy-duty 210D PU-coated nylon, a noticeably tougher and thicker fabric than the 30D siliconized Cordura® on the Ultra-Sil version. The trade-off is weight: you gain abrasion resistance and give up a couple of ounces.\u003c\/p\u003e\n\u003ch3\u003eWhich size Sea to Summit Compression Sack should I choose?\u003c\/h3\u003e\n\u003cp\u003eThe Sea to Summit Compression Sack M (stscompsackm) sits in the middle of a five-size range that runs 6 L (XS), 10 L (S), 15 L (M), 20 L (L) and 30 L (XL). The M is the common choice for a three-season sleeping bag or a bulky insulated jacket; go up to the L if you are packing a winter bag.\u003c\/p\u003e\n\u003ch3\u003eIs the Sea to Summit Compression Sack M waterproof?\u003c\/h3\u003e\n\u003cp\u003eNo. The Sea to Summit Compression Sack M (stscompsackm) is a compression sack, not a dry sack. The PU coating sheds light moisture, but the seams are not taped and the closure is not a watertight roll top. For waterproof storage look at the Sea to Summit eVent or Ultra-Sil Dry Sack range.\u003c\/p\u003e\n\u003ch3\u003eWhat should you pack in the Sea to Summit Compression Sack M?\u003c\/h3\u003e\n\u003cp\u003eAt 15 liters the Sea to Summit Compression Sack M (stscompsackm) suits a three-season sleeping bag, a down parka, or a multi-day clothing kit. Lofty compressible items gain the most from the four-strap system; hard or sharp gear is better carried elsewhere.\u003c\/p\u003e\n\u003ch3\u003eWhere can I buy the Sea to Summit Compression Sack M?\u003c\/h3\u003e\n\u003cp\u003eYou can buy the Sea to Summit Compression Sack M (stscompsackm) at Going Gear, an authorized Sea to Summit dealer.
