It measures 9\" x 20\" uncompressed and weighs 3.3 oz.\u003c\/p\u003e\n\u003ch3\u003eWill a sleeping bag fit in the Sea to Summit Ultra-Sil Compression Sack L?\u003c\/h3\u003e\n\u003cp\u003eYes. At 20 liters the Sea to Summit Ultra-Sil Compression Sack L (stsultrasilcompsackl) is the size most people reach for with a three-season sleeping bag, a down jacket plus midlayers, or a full change of camp clothing. The extra-long straps mean you can actually fill it to capacity before compressing.\u003c\/p\u003e\n\u003ch3\u003eWhat is the difference between the Ultra-Sil and standard Sea to Summit Compression Sack?\u003c\/h3\u003e\n\u003cp\u003eFabric and weight. The Sea to Summit Ultra-Sil Compression Sack L (stsultrasilcompsackl) uses 30D diamond ripstop siliconized Cordura® and weighs 3.3 oz, while the standard Compression Sack line uses heavier 210D PU-coated nylon. Both use the same four-strap flip-top-lid compression system.\u003c\/p\u003e\n\u003ch3\u003eIs the Sea to Summit Ultra-Sil Compression Sack L waterproof?\u003c\/h3\u003e\n\u003cp\u003eNo. The Sea to Summit Ultra-Sil Compression Sack L (stsultrasilcompsackl) is a compression sack, not a dry sack — the siliconized fabric 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 does the Flip-Top-Lid do on the Sea to Summit Ultra-Sil Compression Sack L?\u003c\/h3\u003e\n\u003cp\u003eOn a conventional compression sack the four straps cross the opening and tangle every time you unpack. The Flip-Top-Lid on the Sea to Summit Ultra-Sil Compression Sack L (stsultrasilcompsackl) anchors the straps to a hinged lid instead, so the mouth opens clean and the straps stay in order.\u003c\/p\u003e\n\u003ch3\u003eWhere can I buy the Sea to Summit Ultra-Sil Compression Sack L?\u003c\/h3\u003e\n\u003cp\u003eYou can buy the Sea to Summit Ultra-Sil Compression Sack L (stsultrasilcompsackl) at Going Gear, an authorized Sea to Summit dealer.
