What happened to the Cordura Fabrics??

I have used Timbuk2 bags about 13 years ago, i recently bought a custom messenger with cordura fabric a month back and was thinking of buying my girlfriend her first custom timbuk2 but cordura fabrics seems to have been taken out of the BYOB interface.. bring back the Cordura fabric please! in my opinion, its what makes Timbuk2 bags, Timbuk2 bags in the first place!
