The 30 oz capacity and double-wall vacuum insulation keep drinks chilled for hours, and the flip straw lid offers a convenient sip-and-go experience without the bulk of a full bottle. The tumbler balances nostalgia in the Varsity Collection with practical features like a rotating handle and dishwasher-safe parts, making it a reliable everyday companion for commutes, workouts, or long shifts.\u003c\/p\u003e\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e30 oz Capacity:\u003c\/strong\u003e Holds a large volume so you can refill less often and stay hydrated through long outings or work days.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDouble-wall Vacuum Insulation:\u003c\/strong\u003e Keeps beverages cold for 12 hours and iced for up to 2 days so drinks stay refreshingly chilled on long trips.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIceFlow Flip Straw Lid:\u003c\/strong\u003e The flip-up straw allows effortless sipping and snaps closed to be leak resistant when not in use.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDurable 18\/8 Stainless Steel:\u003c\/strong\u003e Built to withstand daily use while remaining 100% BPA-free and easy to clean in the dishwasher.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eErgonomic Handle:\u003c\/strong\u003e The rotating foldable handle makes it quick to grab and helps the tumbler fit most car cupholders and gym machines.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRecycled Lid Material:\u003c\/strong\u003e At least 10% of the lid material comes from recycled fish nets, reducing waste and environmental impact.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eWho It's For\u003c\/h2\u003e\n\u003cp\u003eThis tumbler is aimed at people who prioritize cold retention and convenience: commuters, outdoor workers, gym-goers, and anyone who drinks iced coffee or smoothies all day.
