Dan P.wrote a review of Patagonia Solar Wind Jacket - Men's on March 10, 2013
Familiarity: I've used it several times
The majority of controversy about this jacket seems to be about the fit. For reference, I think it fits EXACTLY like a MHW Monkeyman. A little short in the body, a little long in the arms, kinda snug throughout but nothing that I would call "weird". I am 5'10" and 135, (clearly) pretty thin, with longer legs I guess. A Small fits me perfectly. I can layer a midweight baselayer and midweight fleece (Arc'teryx Appache Cardigan) and do not feel restricted at all. That said, it really isn't too baggy if I just wear a t-shirt or something underneath. I really wouldn't change the fit.
Small is my normal size in Patagonia jackets, with this fitting just a hair smaller than average.
I was expecting this to be a great jacket for casual use, snowshoeing, as a warmer weather belay jacket, etc. because I didn't expect it to be too packable, given the beefier windstopper shell. However, I was wrong, and it's totally packable enough for a lot of backpacking trips, especially in cooler weather where I'd be wearing it a lot, either as a midlayer under a shell, or a semi-active outer layer.
The collar, zipper, drawcord, cuffs, pockets (elevated for pack/harness compatibility), and materials are all perfect.
I'm gonna be wearing this at the crag this spring, chilly mornings in the ADKs this summer, Winter bouldering California, to class, to work, backpacking in NH in the cold, and any other time I wanna fend off the wind with a little worry-free insulation added in.
