MicroLite XP (polyester microfiber) Made in USA 62IN/39IN (Shoulder/Foot) Girth Full Down Collar 9IN Loft, -10° F Temperature rating 32 oz. Down Fill 3 lbs. 2 oz. Total Weight The sun is bright, the air is warm. Spring skiing is the best of both seasons, and that corn snow is great for carving tele's. But when the sun goes down it often takes the spring with it. That's why you're using our new Western Mountaineering Lynx MF Down Sleeping Bag in MicroLite XP. This -10°F bag weighs only 3 lbs. 2 oz. and has a shoulder girth of 62in. It comes equipped with our plump down-filled collar. The V-Block Side Baffle insures perfect down distribution. And the well filled draft tube has a stiffening tape that prevents snags. This efficient bag with 9in of loft is simply a bombshell of insulation and quite possibly the warmest three pound bag on the market.
