Climbing before work in the mornings is great; changing your clothes in the parking lot before work is not. The Deadpoint Shorts by Outdoor Research allow you to climb as hard as you like, brush them off, and head to the office (as long as it's a casual one).
I love the fit of these shorts: plenty roomy and even though they're made mostly from cotton, they have a nice stretch to get you through the toughest boulder problem.
In the video I talk about the sizing and find it right on, if not a little on the big side. These shorts will follow you anywhere and keep you looking good while doing it.
