Even if you don’t wear a hat on your bike, a beanie is the number one comfort item for everyone’s kit bag. The liner wicks moisture and has an ear band around the inside that adds extra warmth plus an additional layer of sweat-wicking protection. Skullcaps offer a close fit for comfort and easily slide underneath a helmet, so you can stay protected as you ride. Known for its thermal properties, this cycling apparel material provides maximum warmth while ensuring a perfect fit.

Protection from the elements under your helmet is key and GOREWEAR have a collection of headwear that does just this. The ergonomic multi-panel design is extended to the nape of the neck to help keep in heat in and prevent a drop in body temperature.

FDX Helmet can also be worn all year round due to its flat seam construction which helps prevent skin irritation. Windproof with extra coverage around the neck, this balaclava is great for those looking for a cheap solution to those winter rides. Designed for every demanding cyclist, this thermal Roubaix fabric cap is the perfect De Marchi cycling gear addition to your winter equipment, offering exceptional insulation on cold and damp days. The only exposed skin the Gore Windstopper Balaclava leaves behind can be covered with a pair of sunglasses—everything else is protected.

An ultralight and breathable cycling cap that will keep the sun out of your eyes on warm days, while working to move sweat away from your scalp for temperature regulation. Sportful’s Fiandre Norain Cap is minimalist—no ear band, no thermal lining—but it’s wind- and waterproof, making it a good option for cool, rainy days. From cycling caps to thermo beanies, these fit underneath your helmet to protect your head from the chill and allow shade for your eyes from low sun during rides. With its low-profile design, the Roubaix Skull Cap winter cycling cap covers all the sensitive areas of the head, including the ears. The brim is longer than that of a typical cycling cap, ideal for keeping the rain off your face, but this one doesn’t offer ear coverage like other winter hats, meaning it’s more conducive to cool, rainy days than it is for downright freezing ones.

The VC Winter Skull Cap is made of the same Thermo Fleece fabric as our winter Bib tights to help keep your head warm during cold winter rides.Some cycling beanies are thin enough to wear under a helmet and are a great way to keep warm on chilly commutes. Our winter's windproof thermal caps are a tight-fit design that offers a 4-way stretch and elasticated adjustable. Therefore, many hats we offer have reflective elements or hi-vis colours for additional safety in road traffic. The cozy Merino Hat is mostly wool with a bit of nylon that adds just enough stretch for a firm fit.
