Which Montii bottle is right for your kids?

A water bottle is a Back to School staple, and we have a range of sizes to suit all ages! 

Our Mini, Original and Mega Bottles will all keep your drinks cool all day, but which bottle size is right for your kids?


All of our MontiiCo Drink Bottles are made from Stainless Steel and are BPA Free, and have double wall insulation to keep contents cool all day!

Keep reading to learn more about our MontiiCo Insulated Water Bottles and how to choose the right water bottle for your kids.


Mini Bottle

Our Mini Bottle is the perfect size for toddlers and those starting school, but are suitable for all ages.

The Mini Bottle has a 350ml capacity and comes with the Sports Lid 2.0 for easy drinking and is certified safe for under 3's.

If your little ones are just starting school, it’s a good idea to check with the school if the kids have access to refill their water bottle. If they can and are able to, then our Mini Bottles are the perfect size! Otherwise, if they’ll need water to last the whole day we recommend our Original Bottle plus Sipper Lid 2.0, which will keep water cool all day! 

TIP: The Mini Bottle is the same size as our Handbag Hero which comes with a Bamboo Lid instead of Sipper Lid. It's the perfect size to throw in your handbag or for anyone that doesn't drink much water throughout the day. 

Original Bottle

Our Original Bottle has a wide mouth opening (4.7cm) which is perfect for popping ice cubes in, to keep your drink uber frosty! It does mean that younger children might need supervision while using their MontiiCo bottle though, or while they adjust to the wider opening – in case of spills.

The Original Bottle has a 600ml capacity and comes with an eco-friendly bamboo lid with water-tight seal. The screw top lid is easy to open and close, thanks to the cool handle that gives a little bit more leverage. We recommend our Original Bottles for Children aged 4+ and is of course suitable for stylish adults!

The bamboo lid on the Original Bottle can be swapped for one of our sipper lids, sipper lid and straw set (Mini and Original size) or an active + lid which are all interchangeable!

Mega Bottle

Our much loved Montii Mega Bottle  is designed for those with a craving for thirst - MEGA thirst!

The Mega Bottle has a 1 litre capacity which makes it great for big water drinkers who can never seem to drink enough water! It's perfect for quenching your thirst on those hot Aussie Summer days. 

The Mega Bottle comes with our eco-friendly bamboo lid but you can add a free pour lid, sipper lid 2.0 or sports lid 2.0!

If you have pretty active kids who might be doing after school or before school training we recommend upgrading them to a Mega Bottle to keep them hydrated all day.



Our MontiiCo Bumpers are an awesome way to customise your Montii bottle to suit your style, and they also help protect your bottle from drops and knocks! 

Our bumpers come in a range of colours to compliment your bottle and come in 2 different sizes. The Mini and Original size Bumper will fit both Mini and Original Bottles but you'll need to select a Mega Bumper for our Mega Bottles, which have a wider base!

Lets talk lids...


We have 4 types of lid for your Montii bottle and they're all interchangeable - awesome! Our Original Bottle and Mega Bottle both come with an eco-friendly bamboo lid with water-tight seal (our Mini bottle comes with a sports lid 2.0 included). If you'd prefer to sip rather than tip, you can purchase our sipper lid 2.0! 

We hope this helps you to choose the best Montii bottle for your kids! Let us know in the comments if you have any questions, or check out our Drink Bottle FAQs!
