The IRON °FLASK Classic Tumbler 2.0 is a double-walled vacuum-insulated stainless steel tumbler available in 16, 20, 24, and 32 oz sizes. It keeps cold drinks chilled for up to 16 hours and hot beverages warm for up to 4 hours. The tumbler ships with two insulated lids: a splash-proof straw lid (with two straws) and a leak-proof flip lid, giving users flexibility in sip style. Made from 18/8 stainless steel with a powder-coated exterior and laser-engraved logo, it features a slip-proof rubber base to prevent condensation rings and reduce noise. The sleek design fits most standard cup holders, and the tumbler is BPA-free. Hand-wash recommended due to the insulated lids. Ideal for: daily commuters, outdoor enthusiasts, and anyone seeking affordable, reliable insulation without premium branding. Mid-range pricing (~$19) makes it a strong value competitor against costlier alternatives.
