Have you ever taken your insulated water bottle out of your bag 4 hours after filling it and found your water still cool? Or your coffee still hot? It's almost magic... but it's actually physics! We'll explain everything. 😊
🧲 What is an insulated water bottle?
An insulated water bottle is made of two stainless steel walls with a vacuum between them. This vacuum acts as an insulator: it prevents temperature exchange between the inside and the outside. The result? Your drink stays at its temperature much longer than a simple plastic bottle.
❄️ In summer: water stays cool
Fill your bottle with cool water (or ice cubes!) in the morning, and it will stay cool for 12 to 24 hours depending on the model. No more lukewarm water at the beach or in the office!
☕ In winter: your drinks stay hot
Tea, coffee, hot chocolate... your insulated bottle keeps your drinks hot for 6 to 12 hours. Perfect for outdoor days, hikes, or simply your morning commute.
💡 Our tips for optimizing insulation
- Preheat your bottle with hot water before adding your hot drink
- Pre-chill it with cold water before adding your cold drink
- Keep the lid tightly closed to maximize insulation
- Avoid leaving the bottle in direct sunlight
