Dehydration of 2.5 percent of your body weight corresponds to a drop in performance of up to 45 percent. Vapur's flexible "anti-bottles" will make sure you stay functioning. Their half-liter size fits into any pocket and won't knock the wind out of you if you land wrong. Plus they're BPA-free and dishwasher safe. ($10-12 depending on size; vapur.us)
