About ION8
Written by the company
ION8 is a British drinkware brand based in Dundee. We make leak-proof water bottles, kids' bottles, travel mugs and flasks — designed so a bottle can go in a bag next to a laptop and stay where you put it. Every bottle in the range is leak-proof. It's the thing we design for first.
Primo — one bottle, three lids
Primo is designed to adapt. Every lid fits every Primo bottle, in every size — Urban for the commute, Revive for training, Roam for the outdoors. Change the lid, keep the bottle.
Triple-wall vacuum insulation with an internal copper coating keeps drinks hot or cold for up to 10 hours, and the outside stays dry — no condensation on a desk or in a bag. Primo won a Red Dot Design Award in 2026. From £29.99, with lids sold separately at £12.99.
Official NBA and NFL bottles
Officially licensed team bottles, built to the same standard as the rest of the range. Same leak-proof lid, same wide opening, in team colours.
We also work with MotoGP and the British & Irish Lions.
Bottles for school
Kids' bottles built for the bag they actually live in. Leak-proof, dishwasher safe, and a wide opening so they can be cleaned properly — not just rinsed. Sizes from 350ml.
Matching lunch bags and slings are available alongside the bottles.
Shop kids' bottles · Lunch bags
Spare parts, not replacements
A worn seal shouldn't mean a new bottle. We stock replacement lids, seals, straws and filters for the current range. ION8 is certified carbon neutral across all operations, and holds a German Design Award and a King's Award.
What to know about ION8
Written by the company
- Leak-proof across the whole range
- Every ION8 bottle, mug and flask is leak-proof. It can go in a bag next to a laptop, a change of clothes or a packed lunch and stay where you put it. It's the thing we design for first.
- Lids, seals and straws sold separately
- A worn seal shouldn't mean a new bottle. We sell replacement lids, seals, straws and filters for the current range, so a bottle can be kept going rather than replaced.
- Hot or cold for hours
- Insulated ION8 bottles use triple-wall vacuum insulation with an internal copper coating. Drinks stay hot or cold for hours, and the outside stays dry — no condensation on a desk or in a bag.
- Bottles for school and lunch bags
- ION8 kids' bottles are built for the bag they actually live in. Leak-proof, dishwasher safe, and a wide opening so they can be cleaned properly. Matching lunch bags and slings are available too.
- One bottle body, three lids
- Primo is our modular range. Every lid fits every Primo bottle in every size, so a straw lid for the commute and a screw top for the weekend work on the same bottle. Lids are sold separately from £12.99.
- Personalised and engraved
- Bottles, travel mugs and flasks can be personalised with a name. These are made to order, so they can't be returned unless faulty.
- Free UK delivery over £40
- UK orders over £40 ship free on Royal Mail Tracked 48, with Tracked 24 available as an upgrade. Europe is free over £60, and the rest of the world over £70.
- Designed in the UK
- ION8 is a British drinkware brand based in Dundee. The Primo range won a Red Dot Design Award in 2026, and ION8 holds a German Design Award from 2024 and a King's Award from 2025.
- Certified carbon neutral
- ION8 is certified carbon neutral across all operations. Products are designed to be reused rather than replaced, which is why spare parts are stocked for the current range.
- Buying from the US
- US customers should order from ion8.com, which carries the core collection and ships domestically. The UK site ships internationally, but shipping costs apply.

Hello Leanne,
A school bottle that keeps water cold, survives the daily drops, and stays easy to clean - that's the trifecta every parent hopes for. Hearing that your son's ION8 is handling the school routine so well (and the inevitable bashing about!) is exactly the kind of real-world feedback we love to receive.
Thanks for the kind words about our customer service and delivery too - it all counts.

Excellent Quality
Excellent Quality, and an added body nys getting the 3rd bottle free. My son preferred the designs on the 500ml, would be great if some of the 750ml had the same designs. Easy to clean and so far they have stood the test of my son dropping it 59 times a day. I would thoroughly recommend

Hello Kelly,
Durability that survives 59 drops a day - now that's the real-world test every bottle needs to pass! Really pleased your son's ION8 bottles are holding up to that level of daily adventure, and that the easy-clean design is working well for you too.
Your point about the 750ml designs is spot on - we'll make sure that feedback reaches our product team. It's exactly this kind of insight from parents that helps us improve the range.
Three bottles sorted, all performing brilliantly, and a bonus one thrown in - sounds like a result all round. Thanks for the recommendation and for taking the time to share this!

Water bottle 600ml review
Ordering was fine, bottles arrived, looked great. I purchased due to the promise of. O leaks and drop proof! Unfortunately on my daughter’s first day at school, hers did not withstand the day. The lid of the bottle broke. clip snapped so the lid will not close. She said she hasn’t dropped it so not sure if it is a fault. I tried to make contact, unfortunately the online submission form won’t allow me to upload the photo and it won’t let me progress with notifying the organisation. AI bot said this has been fedback and someone will be in contact but I’ve not heard anything so far.

Excellent bottles
I started using these bottles for the family about a year ago and they are great. No leaks unless you don't put the lid on correctly (user error!) Fabulous designs so all the family can have their own colours/patterns. I ordered some new ones over the summer break and the order went missing. Inah in customer services was so helpful in ensuring a new parcel was sent out so that my kids still had their new bottles for the start of term. Very happy :)

Hello Charli,
A year of leak-free family hydration, plus Inah stepping in to save the day when your order went missing - that's the kind of journey we love to hear about. Really pleased the bottles have become such a reliable part of your family routine, and that everyone's found their favourite colour or pattern.
Knowing Inah made sure your kids had their new bottles ready for the start of term means a lot to us - she'll be thrilled to hear this feedback. That's exactly the kind of care we aim for when things don't go to plan.
Thanks for sticking with ION8, and for taking the time to share this!

I should have bought these before!
I’ve been using free sports bottles or reusing spring water bottles instead of spending money on decent bottles. …I suppose because of bad experiences in the past with leaks. However these bottles which my grandchildren use are fantastic! Finally got some one handed use, leakproof bottles. Bought 2 of the recyclon versions and had a 3rd free.

Hello Janet,
Finally finding leak-proof, one-handed bottles after years of free giveaways and spring water reuses - what a relief that must be! We completely understand the hesitation after past leaks, and it's brilliant to hear the Recyclon bottles have restored your confidence. The fact that your grandchildren are using them daily and they're holding up perfectly says it all.
Three bottles in the family rotation now - sounds like hydration sorted. Thanks for trusting ION8 and for sharing your experience here.
