Double down on awesomeness.

Fox Racing's Attack Ultra Shorts aren't jammed full of bells and whistles, but they're the lightest, most technically advanced shorts that Fox makes, perfect for serious trail and enduro riding. The high-tech, four-way stretch Ultra Q4 fabric won't bind or limit motion, and the high level of breathability means that moisture has plenty of opportunity to move away from your skin before it becomes annoying.

The seams around the zippered thigh pocket and strategic stretch vent panels are all welded for durability (and rad looks). The removable liner makes the Attack Ultra Shorts as comfortable as spandex tights, but with the dual benefit of an additional layer of protection and the fact that they're not spandex tights.

The other benefit of the removable liner is that you can use it with your other shorts or with pants for hard DH riding when you need more armor but still want a chamois. This is especially nice, because the Attack Ultra features Fox's most advanced chamois, the Evo Race. This is a multi-density, anatomically-minded insert that adds cushioning to absorb shock and vibration while efficiently managing moisture.

The ventilation is the best i felt keeps you cool on hot days.
The 4 way stretch fabric is awesome as it gives you all the motion you can ask for.
