Product Info

The Billabong Ascent STX Pants have a clean look, an ergonomic fit, and a Sympatex waterproof-breathable membrane that's out of this world. Boasting 45k waterproofing, this jacket is just about the water-stoppingest thing you can get your hands on. Stay out all day in nuking pow or pouring rain, it doesn't matter, because precipitation has no chance against the Sympatex. A stretch construction allows optimum mobility, its thoughtful design is filled with pockets and vents, and the materials are made for countless laps at the mountain. You'll be hard pressed to find a harder working pair of pants.
