Part suspenders, part harness, all leather.
Made from supple cowhide, this three-clip piece presents like your standard suspenders in the front, but reveals a badass quilted back panel showing off your shoulders and contours. Detach the front straps from your jeans and then re-clip to the rings on the back piece, and the FK-designed Viper 2.0 changes from suspenders to a beefy shoulder harness.
One size fits most. Ideal fit for heights 5'7" to 6'1", though other measurements do come into play, as well.
