Key Features

Sturdy pinch weld design, and smooth material makes them quick and easy to remove from pockets. Once liquid is gone, can be squashed down to store or easily refilled.

Made from high quality BPA-free TPU material, no nasty taste. Our flasks also come with a free Milton sanitizer tablet.

Flexible but sturdy material allows them to stand up and drain easily after washing. The bite valve is also removable for easy cleaning.

Ultra Runner and YouTube Gear Tester

Slightly longer and slimmer than leading brand, makes easier to access in the vest. Love the different colours, makes a difference for water and fuel and not getting them mixed up. Slightly thicker material which makes them more resistant to punctures.

When you wash them out and stand them on the draining board they stay upright! Nearly half the price too! Would have preferred measuring scale on the back and the teat is not as good as the leading brand in relation to water flow. But overall, what's not to love for nearly half the price!? Harrier's taken the win for me!

These flasks are the perfect fit for my Agile vest and work with perfection every time. I love that they’re built to last and made by a British company that cares for the environment. Liam at Elevate Running. Photo credit Phil Hill @the_phbalance
