Sipping refreshingly cold water from a tumbler and straw is one of the pleasures of spending a sunny day along the beach, by the pool, or at the park, but drinking from a tumbler while out and about too often leads to unfortunate spills. Thankfully, the Contigo luxe insulated stainless steel travel tumbler with spill-proof lid and straw, 18 oz, solves that problem by including a fully sealed lid and straw to spill-free enjoyment wherever you’re headed. The travel tumbler’s unique straw features an inner valve that effectively prevents spills, even if the tumbler is accidentally tipped or dropped. Added bonus? You can take your time and savor every last drop at the optimal temperature thanks to double-wall insulation that keeps liquids cold up to 14 hours. At the end of a long day, you’ll appreciate that the tumbler lid comes off and the straw twists apart for easy and thorough cleaning, and all parts are top-rack dishwasher safe for a no-sweat cleanup.
