This was our fifth lunch bag from Montii co bag. The quality keeps improving. Love the new name label which can’t be removed. These usually last the full year despite brutal treatment by my son.
Great for hot days. We’ll be back again next year.

Still cold at pickup! Great bag! Strong, well made, easy to clean. My kindy boy loves it, easy for him to use. When I check his lunchbox after 7hrs I find things are still cold. Fits his Munchbox perfectly. Would definitely recommend.

Exactly what I was looking for and fits my sons smiggle lunchbox perfectly. I ordered the large straight after because the quality is amazing and I wanted to be able to have different options for packing my sons lunch. Thank you for an amazing product!

The lunch bags are so amazing! Bought the first one my stepson one 2 years ago (yes they can last that long) and now I’ve purchased a medium one myself one for uni! So glad you designed different sizes. The magic of these are the ice packs, still half frozen after a hot QLD summers day! And they don’t condensate! Which is why I got one for uni so my laptop stays safe and my lunch cold and fresh!
I will never purchase from anywhere else!

Lunch Bag FAQ

All of our Insulated Lunch Bags include a perfectly sized ice pack with its own water-resistant cover, so you’re set to keep food fresh and cool straight away.

Each Large Lunch Bag comes with our best-selling ice pack and a high-quality insulated lining. Together, they’ll keep your food fresh and cool for up to 8 hours – perfect for busy school days or long adventures.

Our Medium Lunch Bags include a slightly smaller ice pack, designed to keep lunches chilled for up to 6 hours.

Our Mini Lunch Bags include a small ice pack, keeping snacks and smaller meals cool for up to 4 hours.

Yes – every MontiiCo Insulated Lunch Bag & Lunch Carrier comes with its own dedicated ice pack pocket. This keeps the ice pack separate, secure, and helps maximise cooling power throughout the bag.

All MontiiCo Insulated Lunch Bags come with a sewn-in name label inside, making it easy to write your child’s name directly on the bag.

Please don’t use iron-on labels, as the heat can damage the foam lining. If you’d prefer not to write inside the bag, a bag tag that clips on is a great way to personalise it and help your child spot their bag easily.

MontiiCo Lunch Carriers do not include a sewn-in name label.

Yes – our Insulated Lunch Bags fit comfortably inside MontiiCo Backpacks, with plenty of room left over for books, a drink bottle and other school essentials.

Keeping your MontiiCo Lunch Bag clean helps it last longer and stay looking fresh.

Good news—our bags are machine washable, so cleaning couldn’t be easier! Just remember:

  • Wash them solo in cold water on a gentle, longer cycle (quick cycles with strong spins can be a bit rough).
  • Use a regular detergent, but skip fabric softeners, stain removers, bleach, soaking, or ironing—these can damage or discolour your bag.

Got a stubborn stain? Mix a little laundry powder with water to form a paste, gently brush it onto the stain, let it sit for 15–20 minutes, then pop the bag in the wash as usual. For exact care specifications, check the “Nitty Gritty” tab on each product listing.

Want help choosing the perfect match? Our Lunch Bag Size Guide shows side-by-side comparisons of each size, with internal dimensions and photos, so you can see exactly which Lunch Box fits inside. It makes choosing the right combo quick and easy.

For the best cooling power, freeze your MontiiCo ice pack flat overnight and place it into the dedicated pocket inside your Lunch Bag before packing food. This keeps the ice pack separate from food, reducing condensation while keeping everything chilled.

Yes! We’ve made it easy to refresh your bag without replacing the whole thing.

  • Ice Packs – Available separately, each comes with its own water-resistant cover. Perfect if you need a spare or want extras to rotate.
  • Lunch Carrier Straps – Replacement straps are also available so you can keep your carrier in top shape.

Yes! All MontiiCo Lunch Bags and Carriers come with a minimum 6-month manufacturer’s warranty.
