A little piece of SIRPLUS history, our signature straight-fit boxers have been crafted to perfection over the past decade. Balancing comfort and durability, each pair is designed with a stretch waistband, corozo button fly and rear gusset, ensuring comfort for everyday wear. Embracing our heritage, our boxers are developed from surplus cotton, just as they were on a market stall ten years ago.
