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.

Wow is all that I can say
Wow is all that I can say. I work in a residential house for kids with behavioural problems and disabilities and I reached out to the company to c if they would sponsor us water bottles for our hard working team who are on their feet non stop 52 weeks of the year and to my delight they have said yes. These bottles are incredible and have been a godsend in this heat while looking after our young people! Thank you so so so much

Great quality products
Excellent product selection and range of bottle and accessories. Bought a bottle for my son from a well known marketplace based retailer and then came direct to ION8 for a straw for it.
Both the bottle and straw are great quality, although the decoration has stated to tarnish after going through the dishwasher a few times. The designs are great for kids.
The shipping was reasonable both in cost and time.

I am impressed
I had the bottle for my two daughters just last week. And very impress with it. My youngest on the first day, she already dropped it many times and I was so glad it didn’t leaked.
So far so good. I will update this comment after some time if it’s really good. But yes so far, I am impressed.

Easy replacements
Had a minor problem with a few of our bottles but they were swiftly replaced with the exact same designs. Very pleased and quick responses from Inah. Thank you so much. Will 100% be buying again.

Great bottles
Great bottles. The metal ones keep the drinks nice and cool in these hot summer days, and the kids size one works well in the fridge. They're easy to operate at any age, and just have two parts which makes keeping them clean nice and easy too.

It only took one bottle
I didn't purchase one of our bottles, but I received one from a friend and have been using it nearly every day, which is a great achievement for me considering the fact that my water intake has always been incredibly low or none at all. I just wanted to say it only took one bottle to change my daily habits, and for that I am grateful.
Thank you ION8

Awful
Awful, love the bottle and design but they leak through the air hole when drinking so useless. We then got the straws and they don’t allow you to drink all the juice in the bottle

I bought steel ion8 bottles last year…
I bought steel ion8 bottles last year because my kids kept dropping and breaking their plastic ones and I was buying new ones every few weeks. Since the ion8 bottles they have each had one for the whole school year. They have had a few bumps but still in great condition and I haven’t had to buy any other bottles for school.

Easy to order on line
Easy to order on line. Regular updates re delivery date. The 2 x 600ml non insulated steel was of good quality and the print selected for grandkids names looked exactly like advertised.
Grandchildren loved them.
Would order again from this company.

Great bottle with design that resonates with my son's recent obsession of tunks.

Bottle you won’t regret buying
I have a few of these bottles now they are really good. I love the lockable leakproof lids they really work. I also find the flip top style so much easier on the go than a screw top bottle as you can open them one handed. There is a great choice of colours and designs so you will find something to suit everyone. This time I also purchased some replacement parts new lids and seals they were easy to fit and renewed my older bottles that were starting to show their age and had had a few scraps. They now look ready to go for another few years. So glad I found ion8 and gave them a try.
