Product details

This special material allows the frame of the MAKALU model to be 20% lighter than conventional materials, more robust in mechanical traction and accidental impacts, it also allows the non-deformability at high and low temperatures. Effectively increasing durability over time.

The category 4 lenses of the glacier glasses are made of top quality and optically perfect polycarbonate. Polycarbonate is the material that allows the lenses to be lighter and safer. In fact, in the event of an accidental impact, the polycarbonate unlike glass does not release small fragments that could damage the eye. In fact, polycarbonate is also used for protective glasses. The category 4 lens is a must for those who love the mountains.
