Sir, I must say you lack logic.

I know they don't do climbing, but I only own climbing wear from REI. If I'm going to buy new pants, why wouldn't I just buy these pants that I could use for more than just one activity? That aside, the pants you linked are not waterproof nor long for that matter.

I wouldn't want to roll up my pants in a rainstorm because it is ****ing raining. Defeats the purpose of wearing long pants if I'm still getting wet, no?
