I switch back an forth between the Defender line of pants and the new Denim style pants. I used to wear the Zero’s a lot back when I climbed - they were great as well.. But now that I’m always on the ground logging, I can tell you that Clogger has it figured out! Their pants have always fit great, been lightweight, breathable, and MOST IMPORTANTLY - comfortable!! If they aren’t comfortable, it’s easier to make excuses about wearing them.. Stay safe!
