Burton built the 12L Day Hiker Backpack to easily handle a few hours of backcountry riding without the added bulk of the larger 20L pack. The 12L day hiker still packs all the features that you've come to expect from a Burton backcountry pack; a board carry system, a shovel pocket, a fleece-lined goggle/MP3 pocket, and hydration compatibility. Don't make the mistake of assuming that all of these features equal a heavy pack, though. At just 1.7 pounds, the 12L Day Hiker probably weighs less than your lunch.
