You gotta hydrate, but you don't gotta look like you just walked out of Camp Emporium to do it. The Sparkling Champagne Water Bottle It keeps your drinks cold for 24 hours, hot for 12; has 18/8 double-walled stainless steel; is non-toxic, non-leaching and BPA free; fits a standard 17 oz. cup size; and will never condensate. The mouth is wide enough for ice cubes and drip-free sipping, and it's vacuum sealed to keep liquids and carbonation fresh. Long story short: it's the most amazing water bottle of all time. By S'well.
