Western Mountaineering Ultralite -7C

Size: Regular

The Western Mountaineering Ultralite is a down sleeping bag that is ideal if you are liable to encounter differing climates on a regular basis.

With a 150+cm shoulder girth and an 850+ down fill, this efficient Western Mountaineering Ultralite bag is good from -7ºc to 2+ºc. The full down collar helps to seal in heat around your neck without adding excess bulk, and 450g of high lofting down pumps this bag to 12.5cm. The total overall weight of this very compressible package is a mere 820g! Awarded with the 'Editors Choice' award by Climbing Magazine, USA.

The Brand
More than 40 years ago, two northern California mountaineers came together with a vision of un-compromised excellence. Their inspired dedication and persistence built the foundation of this now globally renowned brand. Western Mountaineering's history is more than just two young men building sleeping bags: even today WM still remains a small independent company, making all of its sleeping bags in the original factory in San Jose (USA), whilst constantly striving to give their customers the finest down products money can buy.

Great product, great service, great price

I bought a Western Mountaineering ultralite sleeping bag and some La Sportiva tx4 approach shoes. Items arrived quickly and really well packaged. Both items were very reasonably priced, indeed the sleeping bag was actually a fair bit cheaper than I'd seen elsewhere. All in all a very positive experience, would 100% use Rock and Run again and have already recommended them to a couple of other people. Top marks all around!

Best Three season Bag

Simply the best three season bag out there. temperature ratings are more realistic than competitors, and the down quality is better than quoted as they use a different system. The anti snag zips are the best.
