I wore Fox gear (kit?) for a long time too. I agree, the Thor line has great quality. I have both Phase and Core pants that seem as though they'll last forever. And they are comfortable too.
Without consciously doing so, I find that most of my kit (it’s fun to use British expressions) is Thor. My Force knee guards and Aftershock chest protector have served me well. I don’t think Thor’s boots are up to Alpinestar standards, however, when new riders ask me about what gear to get, I always suggest Thor T-30’s.
I’m a Thor guy.
