Check out our extensive selection of men’s boxer shorts from all the top brands. The classic men’s underwear style, boxer shorts let you hang loose and allow the air to circulate. So-called because they resemble the shorts worn by boxers (simple really), the majority are made from pure cotton and have an elasticated waist. Perfect for wearing under more classically cut trousers, such as suits and chinos (and not great with tight-fitting styles), boxer shorts have been scientifically proved to help your sperm count. Boom!
