Niko and... C-1 style pocket vest, Free size. C-1 originally refers to the US Air Force equipment specification, officially known as the C-1 Survival Vest. It was a vest worn by fighter and bomber pilots to store survival equipment (maps, knives, first-aid kits, etc.) to help them survive after ejection or emergency landing. This vest, with its multi-pocket, functional design, is inspired by that C-1 style. This vest also features two large front pockets with flaps and gussets, one chest pocket, and one back pocket. The closure is tied with Japanese cords. It's made of durable 100% cotton ripstop fabric. The size is free, and the width can be adjusted by how you tie the cords. The length is 71cm. I think it can be used in all seasons. Please consider it.
