...Period. I work in a prison, and many's the day that my Black, insulated Carhartt jacket and coveralls were the only thing that kept me from freezing solid on a gate or rec yard.
Funny story:
One day I got assigned to work our medium-custody rec yard, in a station we *lovingly* call, "The Birdcage." The duty station is a five-by-five foot box, mounted twenty feet off the ground on the wall that splits the rec yards for two buildings. It also happens to be on the North edge of the whole farm, so it gets the breeze, firstest and worstest. Well, the temperature was called out at 29 degrees with a wind chill of 13 as I climbed up in there, but lo and behold, there were still idiots out on the rec yard. If they're out, I'm out. So I get up in there, and bundle up under the four or five blankets that are up in the Birdcage, because the heater inside of it puts off a solid *5* BTUs on a summer's day. I leave my water bottle sitting on the sill as I wrap the blankets DIRECTLY ON THE HEATER (PRAYING that they'll catch fire, so at least I'll be warm for a few moments

) and when I turn around to grab a sip roughly five minutes into rec, it is FROZEN SOLID. Fortunately, I was geared up in my Carhartts, so I made it, but it was a "chilling" reminder that the weather doesn't play games.
Okay, anecdote time's over. Get the coat, you won't regret it if you spend ANY time outside working or playing.
