Underhelmets for Winter

Underhelmet caps are an important accessory for winter cycling, as they keep your head and ears pleasantly warm. The caps perfectly fit under a helmet – for comfortable winter riding.

We stock a wide range of warm winter underhelmets in all common sizes, colours and materials by renowned brands like OSE, castelli, GripGrab, Löffler, CRAFT, GORE WEAR, Shimano and more.

Well Protected from the Cold thanks to Underhelmets

A functional cap that fits under a helmet provides additional protection for head and ears. When looking for a winter hat, you should pay particular attention to the material. In contrast to light summer bike caps, thermal hats should be made from a material that keeps you warm. For instance thanks to a very dense and thick fabric. Fleece, for example, is a synthetic fibre that is based on insulating wool but offers improved breathability and moisture management. While wool tends to absorb moisture quickly and thus feels damp and cool on the skin when wet, fleece offers faster moisture wicking and evaporation, so that it still feels comfortably dry and warm during intensive sport activities. Other functional materials also have these properties that protect from the cold while being very breathable.

Windproof Underhelmet Caps for Colder Downhills

Some manufacturers have created something really special. They use windproof materials or membranes for their underhelmets to block cold wind and keep you warm. Windproof underhelmet caps are either made from densely woven softshell material that prevents wind penetration or they feature an integrated membrane that is resistant to draughts. Thanks to the dense fabric or membrane, the caps are also water-resistant. Some well-known windproof membranes are WINDPROOF by VAUDE or GORE WINDSTOPPER which is not inly used for GORE WEAR hats, but also for underhelmets by Löffler etc.

Breathable Underhelmets

One important property of an underhelmet cap is breathability. The body produces sweat when doing sports. As moisture evaporates on the skin, it cools the body. However, this is a real problem in winter! To reduce or even prevent evaporative cooling, it’s important that your underhelmet cap is made from a high-quality material that quickly wicks off moisture to move it to the outside. Thus, you should make sure the cap offers high breathability.

Improved Visibility thanks to Reflective Elements

It’s getting dark early in winter. Thus, you should use high-visibility gear and lights, if you want to go for a spin after work. Reflective elements on your clothes help other road users see you earlier. Therefore, many hats we offer have reflective elements or hi-vis colours for additional safety in road traffic.

As you probably know, no cap is like the other. To keep your head and ears warm, it takes more than just warm material. A windproof membrane and high breathability help protect your body from overcooling. Shop your underhelmet cap now!
