The N-1H Deck Jacket is ready-to-go as-is. It is a dry-cleaning only garment and does not require any pre-soaking.
Please refer to sizing chart to determine which size works for you.
CL's Advice: This jacket is considered true-to-size. I opted for a size 36, my usual size in mfsc N-1H and most other mfsc jackets, with enough room for a thick shirt of heavy sweater underneath. Like most ready-to-wear garments not made from stretch fabric or cut as a poncho pattern, our N-1H might not satisfy everyone’s body type configurations. In general, the consensus is to go with your usual size in mfsc jackets for our N-1H models.
