A documentary shot from front (bottom) to back of a NPEA Re-Ride mochila before its first use. It slips over saddles and can be transferred to a different horse in seconds. It's all leather with heavy stitching and chrome steel. A new mochila is used every year and riders sign it.

It is heavier than earlier versions (including those of 1860-61) and pockets are larger, carrying more commemorative letters. The small pouch at top is for a GPS unit to track the rider's progress.
