40 oz Mega Mug Insulated Tumbler with Handle and Straw - White

In this review the Swig Life 40oz Mega Mug proved to be a practical choice for anyone who wants a large, handled travel cup that actually keeps drinks at a useful temperature. The bottom line: it is best for commuters, parents, and outdoor workers who need a single container that holds a full day of hydration and fits most cup holders. The reviewer found the triple insulated, copper-plated stainless steel construction reliably kept cold drinks cold and hot drinks warm while the handle and straw made it easier to sip on the go.

Key Features

• 40oz capacity: Holds up to 40oz so you can carry enough water or a large iced drink without constant refills during long shifts or road trips.
• Triple insulation: Copper-plated, stainless steel insulation helps keep cold drinks cold for up to 24 hours and hot drinks warm for up to 9 hours under normal use.
• Cup holder friendly: The tapered base fits most standard cup holders so it is easy to use in cars and trucks.
• Handled design: A comfortable side handle makes pouring and carrying the extra large cup steadier than a bare tumbler.
• Included lid and straw: Comes with a removable splash-resistant slider lid, a reusable straw with a silicone flexi-tip, and a silicone coaster base to reduce slips and drips.
• Dishwasher safe: Built to withstand routine cleaning in the dishwasher for everyday convenience.

Who It's For

The Swig 40oz Mega Mug is ideal for people who need a high-capacity insulated cup that travels well: long-commute drivers, parents who want one large cup for the day, and outdoor workers who appreciate a handle when moving between tasks. The large opening and capacity also suit those who like substantial ice in cold drinks.

Those who prefer an ultra-compact bottle or who need a leakproof bottle for backpacks should look elsewhere, since the slider lid is splash resistant but not a fully sealed screw-top. Also, if you need guaranteed all-day ice retention in extreme heat, expect varying results depending on conditions.

Pros & Cons
