The Oakley Ascertain Pants are the perfect complement to the Oakley Ascertain Jacket and the right way to cover your assets if you're a Simon Dumont fan. The 15,000/15,000 waterproof breathable shell material with strategic fleece lining gives you bomber protection from the elements and just a bit of extra warmth. Crotch and thigh vents let your stuff breathe when you're hiking the pipe or stretching your legs to access a new pow line.
