This performance tumbler features patent-pending Sip & Stow lid technology that magnetically stows beneath the vessel during use, combined with 3-way precision insulation to maintain ideal temperatures for both wine and coffee. Crafted from kitchen-grade stainless steel with an aromatic curved shape that enhances flavor, the 12oz capacity means two tumblers carry a full bottle of wine for outdoor adventures. The no-slide base design provides stability on any surface while remaining completely leak-proof and dishwasher-safe.
