POC's Thermal Cap reflects their attention to detail, quality, and informed design. It features a soft brushed fabric on the inner surface next to the hair and skin, as well as extra length around the ears and neck for greater coverage, keeping the cold out on every winter ride. Flatlock seams further enhance comfort on this well shaped construction, which is designed for a perfect fit underneath POC helmets, but works great with most helmets out there as well. A wind- and water-proof material at the front gives extra protection where it is needed most, while reflective details work to keep riders visible in low light. Let's face it, the POC Thermal Cap is just a great piece you'll want to pull on before every shoulder-season ride.
