Jacket is size small. Bibs are size X-small. I am 5'1 120lbs, and these fit good with room to spare. Originally $500 new. They are worn but still in great shape, no rips or tears. Has a few dirt spots is all. Must be bought as a set. Both insulated. "Medium-weight insulation for perfect balance between warmth and performance (60gsm body, 40gsm sleeves and hood)." Check the Montec website for more detailed sizing info. :) Snowboard, snowboarding, ski, skiing, montec, ski jacket, snowboard jacket, bibs
