Features a gusseted crotch that allows the legs to be spread 180 degrees, a flexible waistband, & a webbing belt that can be adjusted with just one hand. Based on designer Mike Graham's experiences climbing in the 1980s, The Gramicci Pants were conceived as an innovation that embodied every function that a climber could want from a pair of climbing pants. Modifications have been made to update the pants to suit modern needs and tastes, including added room around the hips, front opening specs, and right and left back pockets. These colorful men's pants are made from tastefully dyed organic cotton twill that is highly durable, elastic and resistant to damage caused by strenuous movements. These are the classic Gramicci pants much loved by climbers and others for many years, but these pants feature a two-toned coloration that creates a unique look.
