Stanley fans, meet the upgraded IceFlow 2.0 Tumbler! This 40 oz beast is built for serious, on-the-go hydration. The star is the new Flip Straw 2.0 lid – just flip it up for a quick sip from the built-in straw, and snap it shut for a leak-resistant seal that's safe for your bag or car. No more spills! Thanks to double-wall vacuum insulation, it keeps drinks cold for up to 20 hours and iced for days. It's made from durable, BPA-free 18/8 recycled stainless steel, so it's tough and eco-friendly. The handle is large and comfortable for carrying, and the base fits standard cup holders. The wide mouth and removable spout make it easy to clean (and it's dishwasher safe!). Whether you're commuting, at the gym, or just need a giant cold water supply by your desk, this tumbler has you covered. Stay hydrated in style and convenience.
