The Kryptek Tactical Rugby Shirt is a hybrid design from the SS Ruby shirt designed to be worn under body armor. The body of the Rugby Shirt is a Nylon/Cotton Ripstop fabric with no-melt, no-drip, moisture-wicking properties designed to dry quickly and breathe to keep you dry and comfortable for maximum comfort. Kryptek's patent-pending Rugby style neck and collar eliminate a zipper digging into your chest while wearing a plate carrier. The sleeves and shoulders are NYCO 70/30, made from a lightweight, abrasion-resistant fabric to provide extra durability. The sleeves have pad-compatible, anti-abrasion elbow patches and zippered Velcro storage pockets on the upper arm that provide easy storage and access to gear.
