Core Trousers is made up of two broken twill chinos. The Korshavn Broken Twill Chino is cut to a regular fit, and the Nordmarka Broken Twill Chino to a wide fit. The chino began as military uniform trousers before becoming a fixture of everyday dress.

Both are constructed from organic cotton with a broken twill weave and are garment dyed, which gives a rich colour while also pre-shrinking the fabric. They share their cloth with the Arresskov Broken Twill Overshirt, so trousers and overshirt can be worn as a matching pair or separately.
