Collapsible Soft Flask - Leak-Proof Running & Cycling Water Bottle

This collapsible soft flask is built for people who move — runners, cyclists, hikers and anyone who wants water on hand without the bulk. Made from food-grade TPU with a narrow-mouth nozzle, it stays leak-proof when sealed, has no plastic smell, and folds flat into your pocket the moment it's empty. Simple, light, and genuinely easy to live with.

Folds away when it's empty

As you drink, the flask compresses down — no sloshing, no rattling, and when it's done it flattens small enough to slip into a running pocket, vest or bag. You barely notice you're carrying it.

Leak-proof and comfortable on the move

The narrow-mouth nozzle seals securely, so it won't leak in your bag when it's shut. It sits comfortably in the hand while you run and is easy to sip from mid-stride, which is why it suits half-marathons, long rides and trail days.

Food-grade TPU with no odour

Made from food-grade TPU using a hot-pressed process, so there's no plastic taste or smell — just clean water. It's lightweight, flexible and holds up to being squeezed, folded and packed again and again.

Tried & Tested by us

We filled it, sealed it and checked it holds without leaking, and confirmed there's no plastic odour straight out of the packet. It's a soft flask, so it's meant to be squeezed and folded rather than treated like a rigid bottle — used as intended, it does the job well.

FAQ

Does it leak? No — when the nozzle is closed and sealed it's leak-proof, so you can pop it in a bag or vest without worrying.

Which size should I choose? 150ml suits short runs or carrying gels, 250ml is a popular all-rounder, and 500ml is best for longer runs and rides. Many people keep more than one.

Does it taste of plastic? No. It's hot-pressed food-grade TPU, so there's no odour or plastic taste.

Does it fold up when empty? Yes — it collapses as you drink and folds flat to fit in a pocket or vest once empty.

How durable is it? TPU is flexible and holds up well to repeated squeezing and folding. Treat it as a soft flask rather than a hard bottle and rinse it after use to keep it fresh.

How do I clean it? Rinse with warm water and mild soap after each use; let it air out before folding it away.
