Crafted from 100% recycled 304 stainless steel, the Vortex Calix Ceramica Duo unites responsible design with sensory refinement. Its quadruple-wall architecture— recycled steel exterior, vacuum-sealed Coppertech© copper layer, inner steel chamber, and seamless ceramic lining—eliminates metallic aftertaste while resisting stains and odors. An outer powder coat finish adds scratch resistance and a soft matte elegance, all wrapped in a silhouette inspired by the ocean’s spiral grace.

This four-layer system maintains temperature with precision: 18 hours iced, 12 hours cold, 4 hours hot. The plant-based ECOZEN® lid transitions quietly between a discreet straw port and a clean sip opening—both fully leak-proof—adapting to every moment without compromise.

A discreet optional wrist loop integrates into the cap to move effortlessly through the day. Vortex Calix Ceramica Duo—where sustainability, thermal intelligence, and pure taste flow as one.

Size: 8 Ø x 15.4 cm ( 3.1 x 6 inch).
