Montbell VersaLite Sleeping Bag

Jump to: Our Verdict / Features / Specifications

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.

Western Mountaineering says

This Versalite is the warmest in our ExtremeLite™series! A solid 3-seasons of bike touring or kayaking is at your fingertips with this bag. The VersaLite sports 20 oz. of high lofting 850+ goose down for 6″ of loft and a temperature rating of 10°. A “Super” Full Collar will seal in the warmth and protect you from the cold. 62″ of shoulder girth is roomy enough and the total weight is only 2 lbs.

Our Verdict

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.’
