Say goodbye to helmet hair! This stylish cap is designed to fit perfectly under your bike helmet – just remove your helmet and leave your cap in place! When it isn’t needed you can pop it in your pocket, the foldable brim will regain its shape as soon as you put it on again. The mesh sweatband on the inside will keep you feeling fresh, and the 180-degree reflective strips will make sure you are easily seen in low-visibility conditions.
