Purchased from an authorized retailer three years ago. The inside is nylon and very warm. I think it's equivalent to a Japanese size L. It's in excellent condition as I've hardly worn it. Price negotiations are possible. Same-day shipping available. Features a hooded black nylon jacket with zippered pockets. - Brand: LACOSTE Lacoste - Size: US M - Color: Black - Style: Hooded Jacket / Mountain Parka - Features: Zippered Pockets Thank you for looking.
