This Quencher H2.0 is generously sized (but not oversized) and features an easy-to-carry, comfortable handle and a narrow base that fits into most cup holders. Long day of meetings? Rowing class? Trip out of town? The sturdy 30-ounce recycled stainless steel tumbler is up to the hydration challenge. The double-wall vacuum insulation keeps your water cold for 9 hours and iced for 40 hours. And to top it off, there's an advanced FlowState lid with a swivel cover that offers three positions: a straw opening that resists splashing and has a gasket to keep the reusable straw in place, a drinking opening, and a fully enclosed top.
