Constructed of recycled stainless steel for sustainable sipping, our 40 oz tumbler offers maximum hydration with fewer refills. Commuting, studio workouts, day trips or your front porch—you’ll want this tumbler by your side. Thanks to the vacuum insulation, your water will stay ice-cold, hour after hour. The advanced lid features a rotating cover with three positions: a straw opening designed to resist splashes while holding the reusable straw in place, a drink opening, and a full-cover top. The ergonomic handle makes for easy carrying, and the narrow base fits just about any car cup holder.
