On the water, sun protection is crucial, and Shimano's new line of headwear is made to keep you secure, comfortable, and cool under difficult circumstances. This season, there are four new sun-smart designs to keep the sun off the water. All Shimano headwear is made with premium quality materials and attention to important high end design features. Sun protection is provided by the Shimano Soft Stretch Legionnaire helmet cover, which is UPF30 rated*. Polyester cloth dries quickly and can be dampened to maintain cool in humid settings. Functional strengthened non-corrosive press studs that connect the flaps and adjustable elastic webbing that holds the hat firmly in place in the wind are elements of the design.
