I thought I had reviewed this before, thanks recent reviewers to spurring me to give my 2 kopecks.
Although not offering the same degree of moisture transfer as eVENT or Paclite, Patagonia's proprietary W/B material does a surprisingly decent job of deferring the inevitable sauna, so long as exertion levels are not too high ( pushing hard on a prolonged uphill). I tend to combine this w/ a pertex windshell to cover a full range of wet and/or windy conditions, for a total weight of about 10 oz. for the 2 shells---which is ideal for my usage which tends to often be off trail in nature in alpine environments of the PNW and Sierra and most often in UL style.
The cut of the pullover ( size L, I'm 6'2", 180#) is perfect for me , cut large enough for layering over a softshell, w/ a longer cut rear to cover same. Hood is generous w/ a well designed adjustment system.
Mesh backed kangeroo pocket and fairly deep 1/2 zip allows for some venting---wish it had pit-zips but weight would go up. Waterproof zips started stiff but have loosened up. The material, although light, is robust enough to take some abrasion. I don't feel like I need to baby the jacket overly much--which is nice for UL gear. 186 g. in Size L.
I give the Specter Pullover a 4 1/2 out of 5.
