Whether you’ve got little ones heading back to school or bigger ones returning to work, an insulated water bottle is a must-have hydration companion for busy days.

Insulated water bottles use durable stainless steel to keep drinks cool (or hot) for hours – sometimes even days. Available in various sizes, from mini flasks for toddlers and school kids to mega bottles that hold a day’s supply of water, there’s a thirst-crushing bottle out there to suit every age, stage and personality.

Perhaps best of all, reusable insulated bottles are a critical step away from single-use plastic bottles. And we’re right behind environmental awareness every step of the way.

Tips For Buying Insulated Water Bottles

Thirty? Not for much longer! Take a peek at our top tips for buying water flasks that go the distance:

• Look for leak-proof lids - When a drink bottle leaks over a handbag, school bag or lunch box, it can quickly ruin the day. So if you or the kids are always on the move with a bottle in tow, do yourself a favour and opt for one with a leak-proof lid.
• Do you need a carry handle? If you have younger kids, a handle makes bottles easier to hold and helps keep them out of the lost property. For adults, a handle is fantastic for taking your bottle with you on your daily walk.
• Consider capacity - Younger kids aren’t likely to get through a litre of water in a day, so there’s no need for them to lug around a large drink bottle that weighs down their school bags. On the flip side, active teens and adults hitting the gym might need up to two litres to save on constant refills.
• Get enough insulation for your needs - Whether you’re packing a tasty soup for the kids’ lunch or a cold drink to get you through an entire day, ensure you buy a bottle that insulates the contents for enough time. Technology varies a lot between bottles; some insulate for up to eight hours, others for up to 90 hours!

FAQs

Are insulated water bottles worth it?
Yes, if you like your liquid to stay at a constant temperature throughout the day, insulated water bottles are worth it. If you invest in a great quality insulated water bottle, you’ll get icy cold water for hours, without condensation on the outside (which is super annoying for kids when they keep their bottles in their school bags!)

What shouldn’t you put in an insulated bottle?
You shouldn’t put certain drinks like hot milk or tea in insulated bottles, because of the risk of bacteria buildup. It’s also not recommended to fill them with soft drinks as it may damage the bottle.

How long should I keep water in an insulated water bottle?
It depends on the individual features of each water bottle – some keep water cold for up to 24 hours. But it is recommended that you tip out any water after a day and wash your water bottle thoroughly between uses.

Can you put coffee in insulated water bottles?
