We have brought back the Mesh Running Cap we invented in 1990, but with a couple of new features we can claim as the first in triathlon! First the unique pocket on the front! It fits credit cards, hotel keys, driver license, ID, a folder $20.00 bill, most car keys, even a slim MP3 player! Our pocket is low profile with no velcro. Things stay in place simply from the innovative design and shape of the pocket. This great cap has a plastic brim (yes, we were the first to offer this 19 years ago), so it is machine washable. It is made of NanosurfTM and Skin CoolerTM mesh. It has an adjustable closure to give you a comfortable fit. Our Black Skin CoolerTM fabric keeps you just as cool as the white. It inherently has a reflective virtue that is created by a combination of the fibers, the fiber content, and the special way the fabric is knitted. Once the black fabric gets wet it keeps you cool in hot weather. This is no gimmick, we guarantee it works or you money back!
