The Burton Day Hiker—for hiking by day on a skateboard.
With its removable iPod case, skateboard carry, and 15-inch laptop pocket, the Burton Day Hiker is the pack of choice for the technically advanced skater. Carry your deck on this Burton pack when security guards start giving you the stink eye, and free it fast with the quick-release buckles to drop a ten set and go on your way. The Day Hiker Pack includes a hydration sleeve to help you from being overcome by the summer's brutal heat.
I really like this pack. It is a perfect size. I like that I can have my laptop in it and still have plenty of room for other stuff. I also like that you can fold the bottom board straps in when you are not using them.
