Windproof Under-Helmet Cap for Cold Road Miles This slim cycling cap is made for dry, blustery days when a regular cotton cap is not enough. A WINDSTOPPER® membrane by GORE-TEX LABS blocks the wind and shrugs off light moisture, while the low-profile fit disappears comfortably under your helmet. Extended ear flaps and a shaped visor keep the chill and low winter sun in check, and an elastic panel at the back helps the cap sit securely without pressure points. Inside, a soft terry band quietly handles sweat so you can focus on the ride. Small Things – Big Difference WINDSTOPPER® product by GORE-TEX LABS: totally windproof, very breathable, and durably water resistant Curved, flexible visor shields your eyes from low-angle sun without interfering with helmet fit Extended ear flaps add coverage where standard caps leave you exposed Inner terry cloth band absorbs perspiration and improves comfort on longer rides Elastic section at the back of the head for a secure, comfortable fit under most helmets Soft, low-bulk construction that packs easily into a jersey pocket when the day warms up Reflective logo for a bit of added visibility in low light
