Monpu Denim 908 Jacket

A unisex jacket that you can throw on as effortlessly as a shirt.

Made from 8.1-ounce Mont Denim, this fabric sits between the lightweight 45 Petit Denim and the slightly thicker Shirt Denim. Perfect for early spring, it is thin and soft, yet carries the rich depth and character of heavyweight denim. This is 45R’s signature denim, designed to age beautifully over time.

Blending military and tailored influences, this "Jacketter" features bold lapels and structured pockets for a distinctive look. The edges are left stitch-free to create a subtly rounded, organic feel. Even the buttons reflect our attention to detail—crafted by hand from punched-out leather, they add a unique denim-inspired touch. This piece embodies the thoughtful Japanese craftsmanship that defines 45R.
