This Quencher® H2.0 is generously sized (but not oversized) and features an easy-to-carry, comfortable handle and a slim base that fits in most cup holders. Long day of meetings? Rowing class? Outing outside the city? Our sturdy 30-ounce cup made from recycled stainless steel is up to the challenge of hydration. The double-wall vacuum insulation keeps your water cold for 9 hours and ice-cold for 40 hours. And to top it off, there's an advanced FlowState lid with a rotating cover that offers three positions: a straw opening that resists splashes and has a seal to keep the reusable straw in place, a drinking opening, and a fully closed top.
