With the Bike Warm Cap from Vaude, cold ears on the bike are a thing of the past. Thanks to the under-helmet cap, your head and ears stay pleasantly warm on cool days. The high-quality material with a soft, brushed inside is mainly made from recycled polyester - so the knit cap remains breathable. The knit caps are slim enough to be worn under a helmet. A particularly positive aspect is that the Bike Warm Cap is produced in a 100% climate-neutral way. So you can pedal hard even on cold days, because the cold wind can no longer harm you!
