The MegaLite is cut to suit large folks so they too can enjoy the benefits of the ExtremeLite bags. No claustrophobia here with 64` of shoulder girth tapering to 39` at the foot. 12 ounces of goose down provides a temperature rating of 30° and continuous baffles allow you to adjust the fill to suit your needs. At only 1 lb. 8 oz. this is your best friend during a summer bike trip. 

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.  

An example of their attention to detail is their quoted 850+ fill power down used in all their bags: WM quote this figure even though their down generally gets higher ratings in official tests this is because they feel that the official pre-testing preparation enhances the down quality!

* Western Mountaineering state: 'We independently verify own temperature ratings through our own testing, customer feedback and design knowledge. Most of the items in our catalog we have been making for years, which means we have lots of prior knowledge from everyday consumers on what ratings are accurate. We have also EN tested our bags. In every case the EN rating is lower than our posted rating. This means our ratings are more conservative. We do this to ensure that almost everyone will be happy in our bags at the temperature we publish.'
