managed to buy a westcomb neoshell shift jacket at $200 off.

took it for a spin walking up and down steep hills for an hour in the rain, temp 15 degrees wind gusting around 60k's in exposed parts of the walk, other places, light winds.. humidity 99%
pretty good. no sweat buildup. mind you it wasnt hot... even on my back where i had a wet pack there was only a moderate amount of condensation....
no clammy feeling at all in my base layer.... definitely about as breathable a jacket as i've ever worn and arguably the most breathable...
it was blowing pretty strong on top of teh hill and i felt a bit cold in the wind, some people think its because the neoshells let through more air than other rain shells, reviewers often comment about how they feel colder in neoshells than other jackets
the DWR worked great, water just ran straight off....
one issue with neoshells is the hydrostatic head waterproof rating is 10,000m, dropping to 5,000mm over time, cant remember how many washes they said, at least 20,
5.000mm arguably isnt fully waterproof any more or storm proof, at that rating you'd call it highly water resistant...
i was also wearing a gore tex peak cap.. at the end of the walk, the peak cap was saturated inside. i didnt feel hot or feel like i was sweating a lot in the cap so i was surprised about that, it may be an indicator of the difference in breathability between the neoshell and gore tex
the shift is just over 300gm, so i wouldnt recommend if if you're going scrub bashing, and only a napoleon pocket on it. so its not a bells and whistles jacket, westcomb have a couple of other neoshell models with more features.... the switch and the apoc and there are a couple of womens versions as well.. the apoc still only weighs in at half a kilo.
no vents on the shift but there are on the other models which would make them good for warmer climbs given its high breathability...
from what i've read, teh non air permeable waterproof membranes can't breathe in high humidity, they rely on lower humidity outside the jacket to enable the moisture to move through the membrane, whereas air permeable membranes can still let moisture out especially when there is wind to help carry the moisture through the membrane,
this may explain why the gore tex hat was still wet inside when the jacket was dry.
westcomb gets good reviews for the quality of its clothing, has the highest stitch count of any outdoorwear... good replacement warranty if you have paid full retail price... they will still honour the warranty on any clothes bought at sale if you want to pay westcomb the difference between the full price...
i'll be testing it out in tropical climates in sept...
