## Features

- 3 COMBO PACK OF SOFT FLASKS: FITLY's triple pack of soft flasks includes three sizes - a small 5oz/150ml, a medium 8.5oz/250ml and a larger model of 13.5oz/400ml. Our collapsible water bottle 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 flasks shrink as you drink, taking up minimal space and won’t slosh around, making it perfect for runners and vigorous activities.
- SHRINKS AS YOU DRINK: Our collapsible water bottle is uniquely designed to shrink as you drink. This ensures the water doesn’t slosh around, bounce or rattle. The flexible design shapes to your hand & body, meaning the soft flask is never unwieldy. Our flexible water bottle 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 collapsible water bottle 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 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 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.
