Hi there,

I need some opinions. I will get a Western Mountaineering Lynx sleeping bag for the european alps.
I will use it mostly in small double wall tents, in an event bivy for quick overnights and under a tarp.

I asked WM whether or not I could take MF for this purpose, as it's more breathable and reduces
condensation from inside.
They said it will be no problem unless water is applied with pressure (lying on the snow, against a snow cave, etc)
which I do not intend to do.

I figured that if I would have this problem, I could always use either my Event bivy or a lightweight pertex endurance
bivy which is around the same weight as the GWS shell.
With the added benefit that I can remove the cover and the ice that will build up inside the cover, as opposed to the fixed
GWS shell.

What do you think?
