Is the strap strong enough?
The FD range has been launched by Facnor for more than a decade. So we got feedback from its use and have been improving FD in details over the years.
We use high-performance, high-load and low-stretching webbing (polyester for FD90 to 190 and Dyneema for FD210 to 310)
We recommend preserving the webbing thanks to the more appropriate deck configuration, regular rinse and good use (see FD Installation manual)
