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 Nanosurf™ and Skincooler™ mesh. It has an adjustable closure to give you a comfortable fit.
