Oakley's BioZone technology uses differing, strategically placed fabrication to provide you with the optimal amount of insulating warmth, moisture-wicking capabilities, and pure comfort. Combine that with two-layer Gore Tex fabric and fully-taped seams, and boom, you have the Men's 453 Gore-Tex Biozone Down Pant. Built to freeride, the 453 gives you waterproof and breathable performance that's ready to keep you warm, dry, and feeling good while you're stuck on a stopped chairlift in the howling frigid wind, while you're hoofing it up to your backcountry kicker on a bluebird day, or while you're searching for powder lines in the trees. Mesh-lined inner thigh vents help to keep you at just the right temperature no matter what the conditions while a silicone gripper waistband and Lycra boot gaiters keep things in place, even while you're in motion. Reinforced cuffs hold up to the abuse that you put your gear through, and Mt. Baker top map detailing on the cargo pocket just looks damned cool.
