The Zak Designs Kincaid is a 12-ounce vacuum-insulated stainless steel tumbler with a Stitch design. Its silicone sipper spout has a built-in valve that stops flow when no one is drinking, so a tipped cup doesn't spill. That makes it a bridge between a sippy cup and an open tumbler for young kids. Against plain open cups it trades free-flow drinking for spill control; against full sippy cups it looks and drinks more grown-up. Owners rate it highly, and the common gripes are hand washing and the lid's small parts.

This 12-ounce tumbler has a silicone sipper spout with a built-in valve. The valve stops water from flowing when no one is drinking, so a tipped-over tumbler won't spill. It suits active kids and young children moving on from sippy cups who aren't ready for an open-topped tumbler.
The tumbler is made of durable stainless steel and is reusable. It is vacuum insulated to keep drinks cold and to stop condensation from leaving water rings. Do not microwave it.
Hand wash the tumbler to preserve the vacuum seal and keep the artwork bold and bright. The lid can be disassembled and washed on the top rack of the dishwasher.
