Airflow ventilation system.
Vented lens air system.
It creates a constant and regular airflow. The ventilation system moves air freely through the lens chamber, whilst filtering out moisture and snow particles to maximise vision and performance.
Vented lens air system helps equalise the temperature between the lenses, thus reducing fogging. All BLOC goggle lenses are treated with anti-fog serum.
Materials.
All BLOC goggle frames are made from PVC or PU. PVC is a moderately soft material that enables the frame to mould to an individual´s face shape. PU is a stronger, stiffer material better able to cope with harder outer lens materials.
The tough but flexible Polyurethane constructed frame with integrated venting system has a Tri-Fleece, injected Thermo Face Foam for comfort, fit and warmth. The helmet compatible elasticated headband is fully adjustable for the perfect fit.
