The "Category - CAT" number determines the light transmission rate (light transmittance) in the visible range. How well and clearly you can perceive your surroundings depends primarily on the lens you choose.
Replacement Lens TROOP Youth
Our new snowboard and ski goggles The TROOP Youth are also suitable for all wind and weather conditions. The simple pin connector system makes it possible to adapt to the lighting conditions. The glasses can be exchanged quickly and easily by repositioning. The pin-system works exactly the same as with the TROOP Bike (find a tutorial video here).
