Stone Glacier De Havilland Pant proves that not all pants are created equal! Especially, when put to the test of backcountry hunting with a heavy pack. The De Havilland Pants are built with our innovative and patent-pending Contour Waist™ System that allows the user to adjust the waist size of the pants (up to 3″) for an exact fit and make in-field adjustments for layering. As well, unlike other adjustable waist systems, the Contour Waist functions without the bunching of material at the hips which causes discomfort under the waist belt of a heavy pack. Add extra long side zips for venting in hot weather or high exertion situations, and a 4-way stretch, highly breathable and weather resistant textile and the De Havilland Pant quickly becomes a mountain hunters favorite. An athletic fit and articulated knees that are kneepad compatible are just icing on the cake.
