if i'm pretty skinny but i usually buy...
if i'm pretty skinny but i usually buy about a medium in shirts and if i'm pretty tall with long arms should i get a medium or a large. basically does it run small?
I am 5'7" and a slim 150 lbs and I bought this jacket in a medium. I've got a LONG torso and longish arms and the jacket fits great. Plenty of room to layer, but the sleeves are all the way to the base of my fingers. The jacket does ride up a bit, due to the bomber-style elastic on the bottom, but if you have Burton pants with the zip-in feature, the powder skirt will protect your bum from snow. Hope this helps!
