The COS menswear team looked to traditional workwear when designing these relaxed straight-leg jeans, which we've called System. Washed a neutral ecru shade, they are made from 10.6oz denim that blends organic and recycled cotton with linen, giving the fabric subtle texture. No detail was missed – note the COS-branded rivets, reinforced pockets, hammer loop and triple-needle topstitching that's true to original utility styles. For a complete look, wear them with the matching shirt.
