Comments about Camelbak Camelbak Racebak 72 oz. Hydration Vest for Men - 2010 Model:
I was having trouble on my bike with ice forming in my water bottles. This is a great solution, the water is next to my body and stays liquid. I suppose in super cold temps it would act as a heat-sync and steal precious heat from your body. But at about 25 degrees fahrenheit it works great.
