Description
xMeet the ICIOI 40 oz Tumbler with a comfortable handle and a versatile straw spout lid. Built for life on the go, it balances a generous 40-ounce capacity with durable, eco-friendly stainless steel and triple-wall vacuum insulation. Designed to minimize refills and keep drinks at just the right temperature, it’s ready for workdays, gym sessions, road trips, and relaxed days at home.
Thoughtful design meets everyday practicality. The tumbler’s slim base fits most car cup holders, while the ergonomic handle invites easy carrying from desk to gym bag and beyond. The two-in-one lid seamlessly switches between sipping and quick gulps, with a rotatable 360° feature that suits both left- and right-handed users. A dust-proof straw cap keeps the straw clean on the move, and the included straw brush makes it simple to maintain. A scratch-resistant silicone boot protects the base and helps prevent slips on slick surfaces.
