The fourth element mask strap is made from 100% recycled materials. The elastic band is made from recycled rubber and nylon, and the clips are made from recycled ABS (acrylonitrile butadiene styrene) plastic from the automotive industry.
The clips are designed to fit most mask buckles and are compatible with all fourth element masks.
How to attach your snorkel to a fourth element strap Once you have the strap attached to your mask, use the second triglide clip on the strap and pull a small section of the elastic through the buckle to create a loop large enough to insert the snorkel, then tighten to secure it.
