Product InformationThe sun is bright, the air is warm. Spring skiing is the best of both seasons, and that corn snow is great for carving teles. But when the sun goes down it often takes the spring with it. That is why you are using our new Lynx in MicroLite XP. This -10 degree F bag weighs only 3 lbs. 2 oz. and has a shoulder girth of 62. 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 9 of loft is simply a bombshell of insulation and quite possibly the warmest three pound bag on the market. Lynx MF Sleeping Bag - 5'6" Right Zip
