The main fabric of the UBACS shirt is made of stretch-kulir material (95% cotton, 5% elastane), the sleeves are made of ripstop (65% cotton, 35% polyester).
The central part of the shirt provides freedom of movement. The fabric on the collar, shoulders and sleeves gives the necessary density and durability to the shirt and allows for comfortable and clear tactical and combat missions.
UBACS sleeves have soft velcro straps for chevrons, velcro pockets (for documents and small personal items). The neck closure is a zipper.
