What materials are your tumblers made of?
All Sip Unity tumblers are crafted from high-grade stainless steel with a powder-coated finish. They're BPA free and built to handle daily use without losing their edge.
How long do they keep drinks hot or cold?
Thanks to our double-wall vacuum insulation, drinks stay cold for up to 12 hours, and up to 24 hours with ice; while hot for up to 6 hours. No matter where your day takes you, your drink stays just the way you like it.
Are the tumblers spill-proof?
Yes. Our locking lids are 100% spill-proof, so you can toss them in your bag without a second thought.
