If you feel claustrophobic in a hood, miss that turtle neck Grandma gave you when you were 8, or just like 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 bathroom breaks, and Air Tech fabric wicks moisture to keep you warm.
