The Ulrik overshirt from Norse Projects uses a unique 'wave' dying process to achieve its characteristic look. It then is treated with a DWR (Durable Water Repellent) to keep the elements at bay and further enhancing the qualities and things to like about this piece.
Two chest pockets, a rear box-pleat for movement and front panel detail round it out, but it's that Wave dye process that elevates this overshirt over its rivals.
