The CAT EYE COMBAT HELMET CAMO RETENTION BAND is made of a thick and strong Polyester elastic webbing band. Measures 24'' X 1/2'', the camo band helps secure the camouflage ACH/MICH helmet cover in place on all Advanced and PASGT Combat Helmets. Cat Eye bands feature twin glo-vinyl luminous strips 1'' x 1/2'' to reflect and glow at night for friendly identification and safe patrolling. When not needed, reverse the elastic band.
