I absolutely love this jacket, I wear it everyday. On its own it can handle around 35 degrees and up, but when the gauge dips below that point, just throw on a sweatshirt underneath and its bomber. I'm 5'11 160, I got a large and it fits perfect, not as snug as I've heard others say but it works for me. I personally love the color, no one else has the same jacket as I've got, and it goes with most articles of clothing streetwise. Technically it's amazing, blocks about 90% of wind, vents great on hikes, I've even used it snowboarding as both a shell and a baselayer. Couldn't ask for any more, maybe some velcro on the cuffs to close those off, but still my favorite jacket right now.
