Ergon has redesigned two of its three backpacks.  The BC1 (left) replaces the BD1 and the BC2 (right) replaces the BD3.  Both are very similar but with generally sleeker, cleaner appearances.  The Ergon packs features sturdy waist belts with swiveling shoulder harnesses to help the pack move with your body during the normal (or not so normal) contortions you go through when mountain biking and hiking.
