"Heavy-duty" doesn't even begin to cover it. If you need a mug that can chew up a quarter and spit out dimes and nickels, this fully leak-proof and QuadVac insulated, one-finger carry Master Series mug is your new best friend. We mean that metaphorically, though mugs can't chew things.

Highlights:

• 1.0 mm 18/8 stainless steel, BPA-free
• QuadVac Insulation
• Leakproof + packable
• Steel-lined lid
• Dishwasher safe
• Steel carry loop
• Car cup compatible
