Review: Filled it with water and left it on the counter. It leaked. Tried to tighten it up even further, kept leaking. Useless
Review: Después de probar varias marcas y precios, entre ellas las de decathlon, os puedo asegurar que esta pequeña y flexible botellita es cómoda de llevar en bolsillos de mallas o mochilas de Trail. Lo mejor de todo es que el agua NI SABE a plástico, como si me pasaba con las anteriores compradas. Muy recomendable. También he vomitado la de 500 ml.

## Features

- HYDRATION ON THE MOVE: Our collapsible running soft flask is a compact and eco-friendly way to stay hydrated on the move! The soft water bottle is the perfect hydration tool for active individuals. Our soft water bottles for runners shrink as you drink, taking up minimal space and won’t slosh around, making it perfect for running, hiking, skiing or any rigorous activity.
- SHRINKS AS YOU DRINK: Our running vest water bottle is uniquely designed to shrink as you drink. This ensures the water doesn’t slosh around, bounce or rattle. The flexible design of our hydration flask shapes to your hand & body, meaning the soft flask is never unwieldy. Our flexible running flask features an intelligent bite valve & leak-resistant mouthpiece.
- STAY LIGHT ON YOUR FEET: FITLY’s collapsible flask is purposely lightweight ensuring your light on your feet and not weighted down by unnecessary bulk. At FITLY, reusability is deeply important to us, and our water bladder is no exception. Enjoy limitless use from our portable soft water bottle for running vest that is 100% BPA & PVC-free.
- HYDRATION ON THE MOVE: Our soft flask is specially crafted for vigorous activities such as running, hiking, cycling and climbing. The perfect sporting companion, take it everywhere with you! Our soft water bottle can be folded and tucked into your pocket or bag. Our soft flask water bottle comes in 5 size variations and are freezable so they can double as an ice pack.
- DIRECTIONS FOR USE: We recommend rinsing the flask thoroughly before first use. If you experience taste mix ½ a teaspoon of BAKING SODA with water, shake and rinse. Users have also found the following to be useful: Fill with MILK, shake, and rinse. Add drops of lemon. Let an orange peel or tea bag set in the flask for a couple of hours. To hydrate, simply softly bite the mouthpiece and press the soft flask and enjoy! The harder you press, the faster the liquid will exit.

Storleken var perfekt. Smakar plast när man dricker ur den. Läckte lite då locket är svårt att få på helt rätt
