Facts about Windfree
Wind tunnel tested by KTH – nature’s design, scientifically proven
Inspired by the fur-covered ears of fast animals, Windfree dampens sharp wind noise without losing sound clarity. In independent wind tunnel tests conducted by the Royal Institute of Technology (KTH), Windfree kept the noise level below the harmful threshold of 85 dB – even at 50 km/h – compared to untreated ears. Scientifically proven hearing protection for active outdoor use.
Built for all weather – functionality in every detail
Windfree is designed to withstand wind, cold, and rain without compromising comfort or audibility. Vortex Foam blocks wind noise, Thermal Tech regulates heat, and the sound port provides lossless hearing of the surroundings. The flexible Hyperflex frame sits securely under the helmet thanks to the streamlined Aero Shell design. Everything you need for active outdoor training, all year round.
Wind noise cycling – hear traffic, nature, and conversations clearly
Windfree reduces wind noise by up to 20 dB and makes your bike ride up to 4x quieter – without blocking sounds from traffic, fellow cyclists, or the nature around you. The perfect complement to your AirPods or hearing aid, regardless of weather or speed. Ride safer and hear better, mile after mile, with Windfree’s innovative wind noise reduction for active cyclists.
Universal fit – lightweight, secure, and Scandinavian-designed
Weighing only 24 grams and featuring adaptive geometry, Windfree automatically adjusts to the shape of your head for a secure and comfortable fit, hour after hour. The Memory Tension frame stays firmly in place, while the Climate Control lining with Outlast® technology keeps your skin comfortable all day long. Developed in Sweden for high quality you can trust.
Vortex Diffuser Foam – quieter wind, clearer sound
The porous Vortex Diffuser Foam structure (98% porosity) disperses wind sound waves before they reach the ear and blocks up to 80% of wind noise. The result is a unique technology that reduces the annoying wind whistle – while keeping traffic, conversations, and natural sounds clear. Smart material technology that makes a difference on a bike ride, run, or hike.
