I'm just another newbie, but here's my 2 cents worth, based on limited experience. Last June my buddy and I hunkered down on Hood for about 24 hrs, with snow, freezing rain and probably 40-50 mph winds, in an REI quarterdome tent. We got alot of wind and some snow inside thru the mesh tent walls. The day before when we hiked up to the triangle moraine, it was sunny and temps in the 40's, so things can change quickly even in summer. To its credit the tent held up, but especially after going online afterwards and seeing that shortly after we bailed there were gusts up to 91 mph, we decided we needed something with less mesh and so I bought a NF Mtn 25. It's probably overkill, and I know there are tents just as storm-worthy which weigh less, but we'll try it out on Baker soon. So I guess I have to agree w/ Lou Whittaker that saving weight in a mt tent by using alot of mesh, is like saving weight by drilling holes in your spoon. Many many times I've wondered about what we'd have done if we'd stayed another night up there, and the tent would've ripped to shreds......in the dark, 91 mph winds, 2 feet of new snow,and the temps dropping.
