Swig Life Prep Rally Mega Mug 40oz Insulated Stainless Steel Tumbler

Forty ounces of cold brew still ice-cold at noon — that's the practical premise behind the Swig Life Prep Rally Mega Mug, a 40oz insulated stainless steel tumbler built for the kind of day that doesn't pause for refills. The construction tells you what it's about before you even fill it: 5mm 304-18/8 stainless steel, triple insulation combining double-walled, vacuum-sealed, and copper-plated technology, and a condensation-free exterior that stays dry on your desk or in your car. For the commuter heading out of Ashburn before sunrise or the afternoon that stretches long past lunch, this is the Swig Life insulated tumbler that holds its ground.

• 40oz capacity with cold retention of 24+ hours and hot retention of 9+ hours — morning coffee or all-day ice water, without compromise.
• Triple insulation technology: double-walled, vacuum-sealed, and copper-plated construction for sustained temperature performance.
• 5mm 304-18/8 stainless steel body — nonbreakable and built to travel, with a condensation-free exterior that won't mark surfaces.
• Comfort-grip plastic handle sized for a secure hold whether you're moving through a parking lot or settling in at your desk.
• Silicone base that is slip-free, scratch-free, and noise-free — no dragging sound across hardwood, no skidding on a car console.
• BPA-free X-Large Lid with a removable slider, designed to be disassembled fully for cleaning.
• BPA-free plastic straw with a removable silicone flexi-tip included — straw use is intended for cold beverages only.
• Fits most standard cup holders, including vehicle consoles sized for large-format tumblers.

The Swig Life Prep Rally Mega Mug is hand-wash recommended — remove the lid slider and silicone straw tip before cleaning, as both detach specifically to allow thorough rinsing without residue buildup. The stainless steel body can be cleaned with a soft bottle brush and mild soap; avoid abrasive scrubbers that could compromise the exterior finish. Keep the copper-plated insulation layer performing at its best by air-drying the tumbler upside-down with the lid off. This Swig Life 40oz stainless steel tumbler is not dishwasher safe — a small concession for drinkware engineered to hold a full day's worth of temperature.
