Graphene Crew Color: Navy Size: L Worn twice for casual wear in the city. I'm selling it because I don't wear it anymore. This is a piece from a collection that utilizes the benefits of the high-performance material "Graphene Grid Fleece." The crew neck model features distinctive large diagonal waist pockets, which are at the same angle as the ventilation of the TB JACKET and TSURUGI JACKET. When worn together, you can experience a coordinated ventilation effect.
