0.4L Oval Bottle with Karabiner

Nice enough, convenient shape. It is oval, the title should be a giveaway but I'd hoped it might be concave on one side, a bit like a hip flask. That's my stupidity though. The plastic/silicon seal looks very thin but seems to work well - no leaks after a week or two of use.

Great for the grandchildren to use in school. Robust and the shape makes them ideal to fit in a school bag. The karabiner also prevents the bottle falling out of school bags.

Light weight, strong, functional and very cool according to my teenage son.

Good size, fits nicely in side pockets of rucksack and jacket pockets.

Fits the outside side oocket of my day rucksac perfectly.

Handy to fit into your ski jacket pocket.

Very tough. Good for a school bag.

Practical, sturdy fluid container
