Pros: removeable hood and skirt, breathability, weight
Cons: long pocket zippers, no pocket on sleeve for pass
Wanted a new lighter shell that breathed better and had a removeable hood. Looked at the Arc'teryx Sidewinder SV, but didn't like the hood that would not come off, and the price. This was retail listing for $300, but seems to be selling for about 75 less in early 2012, well less than 1/2 of the Sidewinder too.
Jacket is very light,only about 6oz/171.5g more than the Sidewinder at 1lb, 12.2oz / 799.5g (and I assume that measurement is with the hood). Fit, with the Angel Wings Marmot feature in the chest/shoulders is, to me, between athletic fit and loose fit. Used once so far, on a pretty sunny/warm day for February, and had to peel off my fleece vest, yet had no condensation buildup like I always had with my cheaper TNF jacket. Wasn't real windy, but assume this will be extremely windproof.
The construction is what you expect from Marmot higher end stuff, very well put together, everything has a high quality feel to it. Overall very happy w/the two layer Goretex and the mesh lining. The interior mesh for holding gloves etc is very large, as is the interior zipped pocket. No sleeve pocket for either pass or other small items though. Only downside is that only the women's shell is listed on the Marmot site, so not sure if this will be the last year for this shell.
IF you are looking for a very lightweight shell with a removeable, helmet compatible hood, this seems to be a great jacket.
