About this harness
The Riot Curv is ION's performance hardshell, thermoformed from Curv composite with a flex index of 14/20 — stiff enough for full-power support, with just enough give to stay comfortable session after session. For years it has been the reference harness for big air and powered freeride, refined every season rather than reinvented.
