We wanted to make the quintessential casual sailors jacket but at the same time make it soft, comfortable and waterproof so you never need take it off. The outer is a PU Coated Nylon twill fabric that is taped to produce a water proof measure of 5000mm, and breathability of 5000g/m2/24. The lining is a 160g/m2 Fleece which is cosy yet not overly hot - making this jacket something you can wear on both summer days and winter evenings.
