Jack Adams Stadium Underwear Collection features the world’s first cotton punch-hole fabric. The world’s first knitted cotton punch-hole fabric was developed exclusively for Jack Adams. With a blend of 95% cotton and 5% elastane, this is the most feel-good fabric available in underwear, guaranteed. It feels soft, keeps the moisture away and allows the skin to breath like no other. Because of its knitted holes, this fabric is also much more stretch-resistant, retaining its shape and structure for much longer. Get the true punch-hole feel.
