Stone Glacier De Havilland Pant Granite Grey – Contour Waist System + 4-Way Stretch

Experience the Stone Glacier De Havilland Pant in Granite Grey, built for serious mountain days when conditions demand both warmth and mobility. These pants excel in late-season climbs and extreme cold by combining durable warmth with a highly flexible fit, helping you stay comfortable as you move through wind, snow, and exposed rock.

The Contour Waist System is a standout feature, letting you adjust the waist quickly by up to three inches for a precise fit over layers or thinner baselayers. The combination of four-way stretch, breathability, and weather resistance means you can bend, reach, and switch between trekking and scrambling without feeling restricted.

A thoughtful approach to ventilation keeps you comfortable during punchy ascents. Extra-long side zips unlock airflow when you generate heat on the move, and the athletic cut with articulated knees promotes natural movement. The design also accommodates kneepads for added protection on rough terrain or long approaches.

Weather protection and accessible storage meet practical needs. The fabric is treated with a durable water repellent finish to shed light moisture and wind. Front facing cargo pockets, quiet snaps, and reverse coil YKK zippers offer secure, silent access to essentials while you stay focused on the task at hand.

Why it matters in the field

These pants are designed to adapt to shifting conditions, from chilly dawn approaches to sunlit ridgelines. The fabric blends warmth with a lightweight feel, so you can move freely without adding unnecessary bulk. The combination of a secure waist, flexible fabric, and quiet, reliable pockets supports a range of backcountry activities, from trekking to technical descents.
