The North Face Muchu Pant
Here's what other sites are saying:
The Muchu Pant from the North Face is a technical pant with a slight stretch to give you comfort and mobility. The alpine cut is slender and slightly tapered from the knee to the cuff so you get a performance oriented fit that doesn't trip you up. Articulated knee panels make for restriction-free high stepping and climbing and a fixed waistband sits comfortably under pack hipbelts so you can keep on trekking.
