The materials are great. Shells slide on/off effortlessly. It's great alone and I use it for business travel to snowshoeing. Sheds light rain quite well, great fit, packs small. SOME of the colors are rather contrasty between the materials which might be an issue for some. It's the "layer" I've been searching for, for a long time. Great piece.
Patagonia has done a fantastic job with this particular piece. I'm 5'11'' 145lbs and went with a Medium. I tend to prefer more athletic (trim) fitting garments and this jacket fits perfectly for my taste. The jacket performs quite well from 30 degrees with a light base layer to 60 degrees in active pursuits. Interior fleece is soft and the exterior allows the jacket to move freely under a hard shell. All zippers are easy to open and close with or without gloves.
This is a good product, but I dont know if I would buy it again. I dont get very cold and this is usually overkill if over a base layer or under a shell. I still like it, i just don't know when to use it. If I got it again I would get the hoody, and I would use it when if it was very cold, as insulation, or a stand-alone over a cap 1 on a super windy, otherwise dry day. Lighter than a R1, and more versatile, but with my current pieces I havent found a time to pull it out other than walking around.
