## 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.

## Questions & Answers

**Q: Can a sawyer mini or like be used with this product? would be perfect size for my grandson's outdoor pack.**
A: Just tried it on the 150, the sawyer mini and sawyer squeeze don't fit. They're both a hair too small. It looked so promising. If Fitly made the threading a little smaller it would fit.

**Q: What are the dimensions?**
A: 5 3/4 in tot length (14.5cm). 2.5 in wide (6cm).
About 1 in thick at the top, none at the bottom to be easily inserted in pockets.
Because it shrinks as you drink, the dimensions are for a filled flask.

**Q: What are the dimensions of the 500ml flask?**
A: The FLASK500 is 8 inches tall by 6 wide.

**Q: How do you clean this? Especially the mouthpiece where I’d assume would harbor germs.**
A: If you look at the mouthpiece closely, it is not difficult to take it apart, wash it and put it back together.  Call us if you need more guidance.

Kan vara bra att veta att man behöver bita på korken för att dricka. Alltså inget lock mer än att skruva av för att fylla den. Funkar.
