Top Secret:
The secret of the Thermo Shields lies in their XL double-lens design with an integrated air cushion. This clever construction ensures temperature stability of up to 60°C difference and effectively prevents fogging – even in the harshest conditions. Whether you're running, cycling, or enjoying winter sports: your vision stays clear and your performance remains unhindered.

Perfect for glasses wearers:
Combined with the OPT Clip PRO, wearers of prescription glasses also benefit from fog-free vision. That’s what makes the Thermo Shield technology a must-have for anyone who refuses to compromise – even in icy weather.
