Ideal for those who wear helmets during active sports such as skiing, mountain biking, ice hockey or parachuting. Once adjusted on your head, it will hold your eyewear firmly in place and fits comfortably under your helmet. It gives you the option of switching between the helmet strap and temple arm configuration dependent on your sporting needs.
This particular strap is unique to the Leader Jam'n sports eyewear range. It is inserted by unscrewing the temple arms, clicking the strap in place and re-inserting the screw. Unlike many other attachments, this ensures that the strap will never detach from the frame and provides a robust solution for those who are concerned about the movement of eyewear during sporting activities.
