My favorites are the Cortech MOD Denim and Icon Victory with Cortech CPX close behind. The CPX are somewhat water resistant, and the zip off legs are kinda nice when it's warm (after you get off the bike).

Since I banged my knee though, I hate that none of them have good knee armor. The MODs have removable armor, but it moves too easy. I've started wearing my Icon Field Armor all the time- when I'm not wearing armored leather.
