The size is great and is leak proof as stated, which was very important for me. Great bottle, I only use for cold drinks and it keeps my drinks cold for hours

My son loves it for school

Leak proof and durable, best there is

Bought this big size for my son for football, great size for hydrating and keeps the drink cool. Too big for a cup holder as an adult bit we didnt need to use it for this purpose

Lovely bottle with a great quality finish.
The name engraved on it is so nicely done and I’ve found it brilliant to use all week.
We have a few Ion8 bottles each, so we all have one for any eventuality.

Hardy, long lasting bottles which have kept my water cool whilst out in the sun all day. The only reason I even had to replace my first one was because it was on a horse yard most of the week and took a serious battering over 3 years. Also amazing customer service, the only place I'll ever be buying bottles.

I have had my steel, insulated, 1 litre bottle for a while now. Just bought one for my husband and son. they are brilliant. We travel for work to hot countries and it is so lovely to have cold water that does not have a tainted flavour. The bottle has been left in cars with the external temperature 32degrees C+ and the water is still cold. They are exceptionally easy to maintain and very durable as mine has bounced across a gravel car park (it was full at the time) with little or no damage. I believe they are value for money, you get what you pay for - quality.
