Classic freestyle fit and look with the Boy's Cargo pants. With a couple big cargo pockets, it gives your boy a place to put things (phone, money, ipod, walkie talkie, anything) without having to carry around a backpack--which he will inevitably lose anyway. These pants are surprisingly well insulated but don't feel bulky or cumbersome to move around in. This line of pants is one of the mainstays of Burton's youth gear, for good reason. Good performance, good durability, good price, everything you need and nothing you don't.
