Why choose Mermaid?
Most 40oz tumblers use a press-on lid with an open straw hole. That's why they leak the second they tip in a tote bag or a car door. We built the Flo Tumbler with a screw-on lid, a magnetic seal, and a silicone gasket around the straw, so 40 ounces stays where you put it. Same capacity everyone else offers. None of the cleanup.
40oz Venture Bottle - Denim
Meet Venture, your go-anywhere 40oz stainless steel bottle built for long days, big adventures, and every sip in between. With double-wall vacuum insulation, it keeps your drink icy cold for over 24 hours or hot for up to 12, while the wide-mouth design makes adding ice and cleaning effortless.
The leak-resistant straw lid delivers easy hydration without slowing you down, and the matching silicone base adds stability and grip wherever the day takes you. Finished with a durable powder-coated exterior, Venture is made to move—with you, not against you.
