Sometimes pants are just not enough. The Brooks-Range Mountaineering Armor Suit combines two different Polartec fabrics, Neoshell and Power Shield. The Power Shield is used in the front of the body for better warmth on cold days. For weather protection we use the waterproof / breathable NeoShell in the lower legs. The ankle are trim fitting so you can see your feet better when climbing but big enough to fit over ski / climbing boots.
