The Western Mountaineering Sleeping Bag Expander can be added to your favorite Western Mountaineering sleeping bag to create a bit of extra elbow room, or breathing room during warmer weather camping trips. The bag expander is also great for providing just the right amount of space to squeeze into a sleeping bag with that special someone for some world class snuggling. This sleeping bag expander is technically compatible with Western Mountaineering sleeping bags only, so if you buy it thinking it will work with another brand's sleeping bag and it doesn't, it's your own fault.
FEATURES of the Western Mountaineering Bag Expander
Designed to coordinate with only Western Mountaineering sleeping bags
Instantly provides more space in sleeping bag
Great for creating extra room for warmer weather camping
Also allows you to squeeze into a Western Mountaineering sleeping bag with a snuggle buddy

Works with my Montbell ULSS Down BagsTook a chance and bought the WM Bag Expander because it's half the weight of all the other brands. Needed it to squeeze my spoiled dog in my bag when the temps were too cold for her. Works like a charm. It's a little longer than my regular length Montbell bag but the zippers match so that's what matters. Don't know if it will work with other brands but it works for sure with the older models of the Montbell Ultralight Super Stretch Down bags.

Western Mountaineering makes the finest gear on the planet!This exceeded what I expected, my last expander panel didn't even cover the full length of the zipper, COLD. The only thing I would like to see is a four season (this is three season) product. All in all this company makes top notch gear, you won't be disappointed. Thanks Moosejaw for carrying this!
