That is more than 50% lighter than the standard Sea to Summit Dry Sack of the same volume, which is the whole point of the Ultra-Sil™ line.\u003c\/p\u003e\n\u003ch3\u003eWhat is Ultra-Sil fabric on the Sea to Summit Ultra-Sil Dry Sack 13L?\u003c\/h3\u003e\n\u003cp\u003eUltra-Sil™ is a polyurethane-coated siliconized Cordura® nylon. Siliconizing the fabric makes it slippery, tear-resistant and very light, and the PU coating provides the waterproof barrier. On the Sea to Summit Ultra-Sil Dry Sack 13L (stsultrasildrysackl) it also makes the sack nearly transparent, so you can identify contents at a glance.\u003c\/p\u003e\n\u003ch3\u003eHow big is the Sea to Summit Ultra-Sil Dry Sack 13L?\u003c\/h3\u003e\n\u003cp\u003eThe Sea to Summit Ultra-Sil Dry Sack 13L (stsultrasildrysackl) measures 8.5\" in diameter by 21\" tall and holds 13 liters. It is the L size in a range that runs from 1 liter (XXS) up to 35 liters (XXL).\u003c\/p\u003e\n\u003ch3\u003eHow do you close the Sea to Summit Ultra-Sil Dry Sack 13L properly?\u003c\/h3\u003e\n\u003cp\u003eFold the Hypalon® strip at the mouth down first, then roll the top down at least three full turns before clipping the buckle. The stiffener sewn into the top of the Sea to Summit Ultra-Sil Dry Sack 13L (stsultrasildrysackl) helps the roll hold its shape and seal evenly; fewer than three rolls will let water track in.\u003c\/p\u003e\n\u003ch3\u003eCan the Sea to Summit Ultra-Sil Dry Sack 13L be submerged?\u003c\/h3\u003e\n\u003cp\u003eNo. The Sea to Summit Ultra-Sil Dry Sack 13L (stsultrasildrysackl) has tape-sealed seams and a watertight roll-top closure that shrug off rain, spray and splashes, but like every roll-top fabric dry sack it is not built for prolonged submersion. Double-bag electronics or use a waterproof hard case for that.\u003c\/p\u003e\n\u003ch3\u003eWhere can I buy the Sea to Summit Ultra-Sil Dry Sack 13L?\u003c\/h3\u003e\n\u003cp\u003eYou can buy the Sea to Summit Ultra-Sil Dry Sack 13L (stsultrasildrysackl) at Going Gear, an authorized Sea to Summit dealer.
