- Is the lid leak-proof?
- No. The press-in lid is splash-proof, so it handles bumps and sips but will leak if the tumbler is tipped or laid on its side.
- How long does it keep drinks cold?
- Hydro Flask rates its double-wall insulation for hours of cold retention, and owners report ice lasting most of a workday. Hot drinks stay warm for a shorter time.
- Does it fit in a car cup holder?
- Often not. The 40 oz body is tall and wide, so check your cup holder diameter before buying; many owners use it in a holder-free spot or a larger adapter.
- Is it dishwasher safe?
- The tumbler body is best hand washed to protect the finish, and the lid should be hand washed and air dried. Check the care card that comes with it.
- What comes in the box?
- One 40 oz tumbler with its press-in sip lid. No straw or extra lids are included.
