Ultimate Direction Xspurt (2001):
An outstanding choice for cycling on the road or the trail, the XSpurt features a 96 fl. oz. patented Roll Top SportTank that is held snugly against your body through a series of compression straps and a CoolMax-lined padded shoulder harness system. Pack features include an exterior tool pocket, zippered quick-access pocket and over 450 cubic inches of room for a jacket and lunch. One important tip to remember when you load your SportTank: Hold the bladder upside down and suck out all the air before placing the system in your pack. This will minimize water slosh later during your outing.
