Western Mountaineering bag materials: Microlite XP vs. Gore Dryloft

Dave,
I have this same WM bag and like it very much. This is the sleep system I use for winter snowshoeing adventures. The GWS shell adds a little weight but provides for around a 5* lower temp rating. The material allows for good down loft and is very durable. If offered at a good price and a 0* rating fits your needs I would not hesitate to pick up this great sleeping bag.

Dave,
I've got one of these, too, and I love it. Technically speaking, the Dryloft/WS isn't as breathable as the microfiber shell. In practice, though, I've never had a moisture problem in the bag b/c of the DL shell. One added benefit of the (albeit heavier) DL shell is that it's remarkably downproof. I think I've lost all of about 5 plumes in 15 years! Go for it.

Thanks guys. Good to get some first hand info like this.

Thom, have you actually used the bag in 0* conditions? How was it? What other pieces of gear were used (sleeping pad, parka etc.)? What temp do you guys think it's usable down to with just a thin baselayer on?

Thanks!

Dave, PM sent.
