for sure! how often would you recommend? for context, im thinking i'll be using the J27 as a daily jacket until early spring at least..
also, i just walked thru 15 blocks of 19F NYC midtown wind tunnels and it (with the J56) kept me plenty warm. a pair of gloves would not be unwelcomed tho. the zippered pockets are rather breathable but you can feel the wind thru the corners of them. when you tuck your head into the tall collar, the wind really doesn't make much of an impact.. and the hood of the J27 with a ballcap is pretty solid too... i've lived in nyc for a bunch of winters now, and this time i finally got home without having my ears feel like they were about to shatter into pieces as soon as i walked into the door. they were cold of course, but none of that frozen sting..
