Best seller, basic and efficient and especially designed for a great wearing comfort:
- Stainless metal frame and glasses bows made of shape memory alloy.
This combination makes the frame enormously flexible and durable.
- Nose bridge and frame are adaptable to the individual face and head shape.

Compared to the plasfun first belay glasses, this classic offers more comfort and will fit better onto your face but costs more :) The choice is yours!
