"Full Description:\nOur most versatile sleeping bag available, in colder temperatures you can cinch down the technical hood, zip up the draft-tube protected zippers and allow the 750+ Ultra-Dry Goose Down to keep you warm. In warmer conditions, the Free-Flow Zip system lets you unzip in different configurations for superior ventilation and even open up flat to turn the Ascent sleeping bag into a quilt on the warmest of nights. All of the above make the Ascent a true three-season backcountry bag, one of very few on the market. Close the snaps at the shoulders, open the footbox zipper and wear the Ascent at camp - hardcore adventures don't have to be hard all the time.\n\nFeatures:\n\u003cul>\n\u003cli>Lightweight, 20-denier recycled nylon shell with a non-PFAS durable water repellent (DWR) finish to protect against wind and moisture\u003c/li>\n\u003cli>Sea to Summit Guarantee is offered for the lifetime of this sleeping bag\u003c/li>\n\u003cli>Option to zip-couple with a compatible Sea to Summit women's sleeping bag for space for two\u003c/li>\n\u003cli>Thermally efficient, relaxed mummy fit with room in the hood to fit an Aeros pillow (not included)\u003c/li>\n\u003cli>You can even close the snaps at the shoulders, open the footbox zipper and wear the Ascent at camp\u003c/li>\n\u003cli>In warmer conditions, the Free-Flow Zip System lets you unzip in different configurations for superior ventilation and even turn the bag into a quilt\u003c/li>\n\u003cli>In colder temperatures you can cinch down the technical hood, zip up the draft-tube protected zippers and allow the 750+ Ultra-Dry goose down to keep you warm\u003c/li>\n\u003cli>Free Flow Zip System offers excellent temperature regulation and multiple sleeping bag configurations\u003c/li>\n\u003cli>Box baffle construction throughout with vertical baffles in the torso to minimize down shift and maximize warmth retention\u003c/li>\n\u003cli>RDS-certified, 750+ fill-power goose down with a non-PFAS Ultra-Dry Down treatment to stay drier in damp conditions\u003c/li>\n\u003cli>20-denier recycled nylon liner for greater comfort\u003c/li>\n\u003c/ul>\n\nSpecifications:\n\u003cul>\n\u003cli>Compressed Volume: Regular: 5.5 liters, Long: 6.4 liters\u003c/li>\n\u003cli>Fill Weight: Regular: 10.6 ounces, Long: 12.1 ounces\u003c/li>\n\u003cli>Weight: Regular: 1 lb. 11.6 oz., Long: 1 lb. 15 oz.\u003c/li>\n\u003cli>Tested Comfort: 38 degrees (F) - ISO\u003c/li>\n\u003cli>Hip Girth (in.): Regular: 57.5 inches, Long: 61.4 inches\u003c/li>\n\u003cli>Shoulder Girth (in.): Regular: 62.2 inches, Long: 66.1 inches\u003c/li>\n\u003cli>Fill: 750+ fill-power goose down\u003c/li>\n\u003cli>Shell: 100% RCS recycled nylon\u003c/li>\n\u003cli>Stuff Sack Volume: 8 liters\u003c/li>\n\u003cli>Fits Up To (in.): Regular: 72.5 inches, Long: 77.5 inches\u003c/li>\n\u003cli>Lining: 100% RCS recycled nylon\u003c/li>\n\u003cli>Zipper Location: Left/Right\u003c/li>\n\u003cli>Sleeping Bag Shape: Mummy\u003c/li>\n\u003cli>Water-Resistant Down: Yes\u003c/li>\n\u003cli>Temperature Rating (C): -1 degrees (C)\u003c/li>\n\u003cli>Temperature Rating (F): 30 degrees (F)\u003c/li>\n\u003cli>Tested Lower Limit: 30 degrees (F) - ISO\u003c/li>\n\u003cli>Sleeping Capacity: 1-person\u003c/li>\n\u003cli>Best Use: Backpacking\u003c/li>\n\u003cli>Gender: Men's\u003c/li>\n\u003cli>Insulation Type: Down\u003c/li>\n\u003c/ul>\n"
