Wearing a cap under your helmet is essential to keep your head and ears warm on cold winter rides.

A cold head and ears can quickly ruin a winter ride, but fitting a warm hat under a helmet can be uncomfortable. This is where a skull cap such as this becomes useful. Just be aware, that if you choose to wear it without a helmet you will look like a cosmonaut.

Mavic claim that the cap features "wind protection and thermal protection with strategically placed windproof fabric and brushed inserts for moisture management and thermo regulation". We found that the holes near the ear aid hearing and offer a degree of ventilation.


Venting on the ear, helps regulate temperature, but also makes hearing easier

Having worn this cap on many winter rides we can confirm it excellent at keeping you warm and is ideal for temperatures ranging from 0ºC to 12ºC. We like the Mavic Winter Underhelmet cap, it fitted under our helmets really well and considering a good thermal cap will last years, it isn't too expensive either.

Our only gripe was the one size fits all sizing. Our testers who normally wear size 'medium' helmets found it a little on the small side, with not all of their ears covered. If you have a smaller head than a male 'medium' this will probably be the ideal fit.
