• DuraSip™ Ceramic Lining: This nonstick, no-mess interior is fused to the stainless steel to provide a classic ceramic feel that resists staining from highly acidic beverages like coffee while remaining tough enough to withstand drops.
• Double-Wall Vacuum Insulation: This over-engineered technology keeps your hot drinks hot and cold drinks cold until the very last sip by creating a thermal barrier that prevents temperature transfer.
• 18/8 Stainless Steel: Constructed with kitchen-grade stainless steel, this mug is puncture and rust-resistant, ensuring it can handle the rigors of any outdoor adventure or daily commute.
• Stackable Design: The specialized base allows you to nest these mugs together, saving valuable space in your kitchen cabinets, camp bins, or travel bags when you are strapped for storage.
• 360: Degree Welded Handle: The heavy-duty handle is securely welded to the body of the mug, providing a firm, comfortable grip that won't break off even if the vessel hits the rocks.
• Hand-Wash Recommended: Advised for all customized products to maintain the quality of the finish.
