Same with Mountain Hardwear's Dry-Q garments. Fabric characteristics seem ideal for warmer (soggy) conditions.
A month or so ago, I purchased (on sale for $238*) the Mountain Hardwear Kepler (Dry-Q) Jacket. After a few Nordic ski outings, a five-hour ascent of Sasse Ridge in nearly two feet of untracked powder, and a recent stormy (avy training) weekend at Yodelin (requiring not much elevation gain but lots of standing around) I believe this is the best mountaineering/backcountry jacket I've ever owned.
In warmer temps, it retains heat but much less so than my Rab softshell jacket and Mountain Hardwear hardshell. In conditions where the jacket can't be stowed, the Kepler's pit zips help dissipate body heat. The hood works very well with and without googles.
On our second day at Yodelin, during the moderately-paced ascent with temps around 20 and no wind, my short sleeve and long sleeve shirts became too warm. I removed my long sleeve shirt, donned my jacket, and started skinning. In short time, my upper body's dampness dissipated.
On our first day, when the wind was blowing hard and snow was falling horizontally, beneath the jacket, I layered using my lightweight synthetic jacket. It blocked the breeze yet I didn't overheat when we began stomping around and digging pits.
Those experiences coupled with its 100% waterproof-ness are the two reasons why it's now my backcountry jacket of choice.
I'm 178 lbs and 5' 10". The large (chest size 43) fits me perfectly with one minor exception: the sleeve's thumb holes are a bit too tight. With another inch or two of (sleeve) length, they'd fit perfectly.
