Slide to pop. Flip to lock. The Wellspring Bottle is push-button hydration that goes everywhere you go. Just grab it by the easy-carry loop and get going. The 32-ounce Wellspring Bottle keeps your water or beverage cold for hours, thanks to double-wall vacuum insulation. To drink, slide the button down, and the leak-resistant lid pops open to reveal the sculpted drink spout. When you&&';;re done, flip the top shut to lock it tight.
