Insulated Bottle FAQ
How long do insulated water bottles keep drinks cold?
It depends on the model, the lid and the ice. Makers give their own figures, and results vary, so check the listing.
Can I put hot drinks in an insulated bottle?
Many are made for hot drinks, but not all. Check the maker’s advice for your bottle and lid.
What size insulated water bottle should I buy?
A mid-size bottle suits most people. A 32 oz bottle suits a day at the desk, while a larger one suits long trips.
Are straw lids leak proof?
Straw lids can leak if the seal is not closed. Look for a lid that locks or has a cover, and check the maker’s claim.
