If you dearly miss that turtleneck you were wearing in your 4th grade school photo, feel mildly strangled by hoods, or just need to let your hair blow in the wind, the Hoodless Ninja Suit is the base layer for you. We highly encourage you to step in, zip up, and enjoy the superior coziness of complete body coverage... with the top down. Trademark Ninja Suit 350 degree hip zip is standard, providing easy-peezy bathroom breaks, and soft Air Tech fabric wicks moisture to keep you warm.
