Here's what other sites are saying:
Here's the deal: you need a great performance shell while out at the terrain park poppin' tricks day in and day out. The solution: Oakley's Shell Deals Jacket - you stay dry all day long in the fully taped waterproof polyester shell while your sweat is still allowed to vent through the fabric, or better yet, through the underarm vents. Keep major mobility since it has a loose cut, plus, don't worry about it flopping around since it has thumbholes at the wrist gaiters and a magnetic hold on the hood.
