Cotton Tech Trench
Technically, this is a Balmacaan (the proper name for a trench coat without a belt, but who's checking?). The partially-lined coat is water-resistant, comes with durable corozo buttons plus eyelets for breathability.
Fits true to size. Ryan is 6'1" and wearing a size M.
50% cotton. 40% polyester. 10% nylon. Lining: 100% cotton.
