Western Mountaineering down gear has an awesome reputation in the US and that reputation is beginning to build on this side of the pond. Very high quality materials design and construction results in the lightest bags available for a given warmth. \nWestern Mountaineering says\nWhen the Sierras or the Rockies are your usual destinations and you need the maximum protection from your 3-season bag, leave nothing to chance with our Antelope. Its roomy 62 shoulder girth allows for comfort and the 7 loft from 26 ounces of high lofting down provides warmth to 5. The security of this bag is sealed with a full 3-Dimensional down filled collar and a robust draft tube. While extremely weather resistant the MicroLite XP shell retains maximum breathability and its down filled collar is sewn with MicroLite XP fabric. These Antelopes take over in early spring and last through late fall. At a total weight of 2 lbs. 7 oz., they are the most substantial 3-season bag available. They are also available in 56 length.\n\nOur Verdict\nWestern Mountaineering down gear has an awesome reputation in the US and that reputation is beginning to build on this side of the pond.
