Have both a leather FXRG jacket and the FXRG cloth versions + pants for the cloth versions. The cloth set has been through some showers and I think is about as good as raingear, but of course has some seepage in places. More versatile than the leather for all-around wear I think. Certainly "breathes" better.
As already said here, the leather is great, warm but can get heavy during in between times (warmer days), but with the vents opened up it's bearable. Great protection with the installed armor.
Never had any problems with the zippers,but maybe I'm just lucky.
