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).
Premium ECOZEN® dual-mode lid
A screw-on lid precision-molded from ECOZEN®—a premium biomassbased polymer drawn from renewable plant resources rather than fossil feedstocks. Its dual-mode architecture transitions seamlessly between a refined sip aperture and a flip straw anchored to a 304 stainless steel tube, each sealed with quiet, leak-proof assurance. With crystalline clarity, exceptional heat resistance, and food-grade purity, it embodies sustainable luxury that honors both ritual and responsibility—without compromise.
Ceramic coating
Odourless, durable, and a breeze to clean—your Calix Ceramica Eco ensures that every sip is as perfect as nature intended.
Optional with wristband
Built to craftsman precision using
food grade 304/304 recycled
stainless steel means it will perform
and look great for years.
