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!
