Hell Team Logo Lanyard Only. (static)
The standard Leonelli lanyards are elastic, which both wears out faster, and tends to get longer with age.
Some people prefer this non-stretchy design. The "OFF" is more positive, and it is less likely to get caught on twigs or similar.
It just needs the loop end to passed through the hole in the top of the Leonelli button and then back through itself for a secure connection.
