BONCOURA Cotton/Nylon Twill "Dog Ear" Sport Jacket (Navy)

Size Guide

Inspired by vintage British Baracuta “Dog Ear” Sport Jackets, Boncoura elevates it to a next-level, high-end “new standard” item.

The cotton/nylon twill is constructed with 70% full grain, long fibre cotton and 30% nylon which is specially developed for Boncoura, the medium weight fabric is densely woven from vintage machines so it is a little bit water resistant and wind proof . The color is naturally over-dyed which will age to a more vintage look with wears and washes.

The silhouette is so simple and elegant. We really love the adjustable cuff and waistband giving you flexibility for changing weather and occasions .

If you are looking for some ‘All-Season’ Sport Jackets, these are some ideal ones!
