Western Mountaineering Lynx MF Sleeping Bag -10F/-23C LZ Navy Blue 5ft. 6in.. 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 the new Lynx in MicroLite XP. This -10 F bag weighs only 3 lbs. 2 oz. and has a shoulder girth of 62". It comes equipped with a 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 over 8" of loft is simply a bombshell of insulation and quite possibly the warmest three pound bag on the market.
