All of our bottles are double-walled, vacuum insulated (also known as thermally insulated), meaning they are suitable for hot and cold drinks – perfect for year round use. The wide mouth opening does mean you need to be EXTRA careful with hot liquids.
MontiiCo bottles provide 12 hours of warming. Some tips to get max warming:
Pre warm the bottle just prior to use with boiling water. Attach lid and let stand for 10 minutes, then empty
After pre warming, fill your bottle, and replace lid for maximum insulation efficiency
Keep lid in place as much as possible to keep your beverage warm
WARNING: Always exercise caution with hot beverages to avoid burns and scalds. Wide mouth bottles are NOT recommended for use to serve hot beverages to children.
