Does it really keep drinks cold all day?

Yes, the double-wall insulated design maintains temperature for extended periods. Most users report excellent cooling performance for 8-12+ hours depending on ambient temperature and usage.

Is it truly leakproof?

The flipstraw mechanism creates a seal when closed, making it reliably leakproof when properly sealed. It's designed for travel and fits securely in car cup holders.

Can I put it in the dishwasher?

Most components are dishwasher safe, though hand washing is recommended to maintain the seal integrity and prolong the tumbler's lifespan.
