Outdoor Research Men's Vantage Pants:
These cotton pants provide cool comfort while bouldering or climbing on warm days when the sun stays high in the sky; the Men's Outdoor Research Vantage Pants feature fabric that allows breathability of your body heat and a bit of spandex and a relaxed fit allow unrestricted movement for technical, high-stepping moves. The wicking, low-profile waistband fits smoothly with a harness and full-length legs protect your skin from bumps and brushes against rough rock.
