My boys love dirt biking and most motocross sports. They can spend hours racing around rough terrains. Because they often do this in summer, I worry about them becoming dehydrated. We all know our kids tend to forget things like this when they're busy running around the dunes. So after nagging Cam about taking frequent water breaks, and hearing "Mom!!", he caved and bought himself the Camelbak M.U.L.E. hydration pack. This nifty bag holds a good 100 ounces of liquid. Plus it's easily refillable.
The M.U.L.E. cost him only $79.99, and he got a free refill reservoir with it, during a special. it has a sturdy waistband with a velcro closing, or wear it as a harness. It has a pocket for Mp3's or even a cell phone, and is constructed of hefty nylon. Two added features I like are the splash guard and the little reflector tabs to help increase visibilty in low light situations.
This is a very good product with lots of features to help any motosport rider stay healthy and safe.
