Yeah - thats when I ran into problems with lift served. High winds on the lifts had me wearing heavier baselayers, which left me sweating in the trees at the bottom of the run (out of the wind). A super thin lightweight baselayer and a hardshell thin puffy with awesome ventilation was the trick (Flylow BA). Kills it for the mountain states. Vent and its almost like running around naked.

Why I am looking real hard at TNF thermoball hybrid.
Removed pic, didn't want to cunt the Micol thread.

MiCol - fair enough. Its my understanding that CFM or direct air permeability is largely based on the least breathable component - in this case I suppose it could possibly NOT be the Neoshell membrane itself? I would think it would be though. Out of your options for #1 - how would you characterize the breathability between each of the fabrics? (darth vader test - try to breath through it)
If you make pants, you should consider add male snaps near the belt loops like Oakley does and add mating female snaps to powder skirts (add removeable ones to the jacket). Killer system - love it. Oh yeah and suspenders are a must. Skiing is really dynamic and the last thing I want is something tight around my waist (usually pop snaps no matter how loose the waist is - moguls or chop and the occassional huck).
By the way, digging the new color options man!

If you have three and one has 100x more resistance than the others you can get away with ignoring the others, but as they get closer in values you have to do the math and pay attention to all of them. Without isolating it, you know this membrane is similar to fabric in terms of flow resistance because it's easily possible to make a fabric with no membrane at all that breathes slower than a light Neoshell.
It sounds like your experience validates the better flow. YMMV, but I prefer better breathing/less sweat to less breathing/more sweat in all circumstances; getting insulation right for temperature is still important, but I'm much more sensitive to it when I'm sweating.
Thats true for calculating CFM between layers, but when talking about fabrics laminated together it changes quite a bit - they tend to act as one layer with the lowest CFM of the bunch. The formula for layering is 1/(1/a + 1/b).
I agree with you when it comes to backcountry skiing but when you add being on lifts in the alpine and wind, I prefer a completely windproof shell, thin layers and large venting capabilities that can bypass almost all of your insulation (can't do that with fleeces/etc.). This way you have minimal insulation (bypassed) when you're warm and no heat-sapping wind requiring you to add lots of midlayer warmth. Stretch-woven softshells suck for liftserved on all but the warmest and calmest days for a reason. Really big fan of insulated hardshells with no-mesh venting for lifts - especially on colder days.
