Our selection of men’s bags resolves the age-old tradeoff between functionality and design. Briefcases, document cases, and messenger bags are classically professional, yet crucially updated in minimalist fabrications. Showing equal unions of style and substance are backpacks, duffles, and weekend bags rendered in uncommonly luxurious leathers. Sleek nylon bags answer the athletic undercurrents of this season’s casualwear, while solidly crafted canvas totes and backpacks elevate utilitarian forms to new levels of quality.
