Incorporating lightweight jackets into your look is a great way to navigate the in-between months. Wear them under heavier outerwear in cold temperatures, or alone when things warm up. The men's lightweight jacket has become a cross-seasonal essential. They're light enough to be layered under heavier outerwear, and can also work as a top layer in warmer climates. Our big range includes light bomber jackets, nylon jackets, men's waterproof jackets, biker jackets and more. And with new fabrics, classically heavy styles now arrive in light transitional weights. And like all JACK & JONES outerwear , the looks are always on-trend, in a range of season-ready colourways.
