## Description

The FITLY FLASKS Combo offers three collapsible water bottles for running, designed for athletes who demand lightweight, portable hydration without bulk. This soft flask running set includes 5 oz (150ml), 8.5 oz (250ml), and 13.5 oz (400ml) sizes that fit easily in jersey pockets, running belts, and pants pockets. The handheld running water bottle design features thermoplastic polyurethane construction that is BPA-safe and PVC-safe for safe hydration during marathon training, cycling, hiking, and skiing. Each soft water bottle running flask shrinks as you drink, creating an airtight seal that prevents sloshing and reduces bulk. The flexible water bottle compresses to a minimal size when empty, making it easy to carry in running vest water bottle holders or standard pockets. The intelligent bite valve mouthpiece has a shortened design that allows faster liquid flow, while the enhanced circular lock mechanism provides leak-proof closure during transport. These collapsible water bottles for running are freezable to double as ice packs on hot days. The running water bottles clean quickly after use and work effortlessly during activity. Ideal for runners, cyclists, and hikers seeking pocket-friendly hydration solutions.

Review: Buon prodotto, comodo - Le utilizzo invece della classica che si sporca continuamente, buon prodotto, vedremo la durata
Review: No leaks! - These are very handy for skiing. I was always worried about falling hard on my cool metal hip flask, but with these, that's not a problem. (And I know what you're thinking but don't put alcohol in them!)

## 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.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Buon prodotto, comodo
*by R***O on 4 August 2026*

Le utilizzo invece della classica che si sporca continuamente, buon prodotto, vedremo la durata

### ⭐⭐⭐⭐⭐ No leaks!
*by T***N on 22 July 2026*

These are very handy for skiing. I was always worried about falling hard on my cool metal hip flask, but with these, that's not a problem. (And I know what you're thinking but don't put alcohol in them!)

### ⭐⭐⭐⭐⭐ Lightweight, small 'footprint
*by J***. on 20 September 2024*

For walks around the neighborhood or short hikes, I hate taking a bulky waterbottle. I don't like having a backpack, fanny pack, or crossbody for sensory reasons, so having a small, lightweight way to carry some hydration was on my list of 'things to find.' Well, I found it! The selection of sizes allows me to take just what i need for that day's particular 'adventure'. Once I have finished the water, it is like I am carrying hardly anthing at all (unlike a water bottle). It easily fits in my pocket full and empty. Drinking from them took a few tries to get used to you, you do indeed have to bite as instructed which feels like a no-no based on past mouthpieces that would tear. These hold up to the biting. I also did a few vinegar rinses to be sure there was no silicone flavor, and that worked well. The mouthpiece does not give or leave a silicone or plastic flavor either, which was important to me. I love these!
