Review: Convenient and Functional Soft Flask for Hydration - I recently purchased the FITLY Soft Flask - 12 oz (350 ml) for my running and hiking activities, and it has quickly become an indispensable part of my hydration setup. This soft flask offers a range of features that make it ideal for anyone needing a compact and efficient water bottle for outdoor activities. The design of the FITLY Soft Flask is excellent. The flexible material allows the bottle to shrink as you drink, reducing its size and minimizing sloshing. This feature is particularly useful during runs or hikes, as it ensures the flask remains compact and comfortable to carry. The flask is also lightweight, making it easy to include in my hydration pack or running vest without adding unnecessary bulk. The build quality is impressive. The flask is made from durable, BPA-free materials that are safe and long-lasting. Despite being soft and flexible, it feels sturdy and capable of withstanding regular use. The wide mouth design makes it easy to fill and clean, which is a significant advantage over some other hydration solutions. The cap and nozzle design are both practical and user-friendly. The cap seals tightly, preventing any leaks, and the nozzle allows for easy sipping on the go. It's simple to operate with one hand, which is perfect for maintaining momentum during activities like running or cycling. One of the standout features of this soft flask is its portability. When empty, it folds down to a small size that easily fits into a pocket or pack. This makes it convenient to carry as an extra water source or for use in situations where space is at a premium. Overall, the FITLY Soft Flask - 12 oz (350 ml) is a fantastic hydration solution for runners, hikers, cyclists, and outdoor enthusiasts. Its durable construction, practical design, and compact size make it a highly convenient and functional water bottle. I highly recommend this soft flask for anyone looking for an efficient and reliable way to stay hydrated on the go.
Review: AWESOME accessory to enhance my runs and keep me hydrated !! - When I first got into running long distance a few years ago I tried so many iterations of bottles - this by far is my favorite! It’s a solid design, holds just the right amount of water for me and fits in my run vest so I can be hands free, plus it doesn’t break the bank. I’ve also weirdly enough put warmer water in it for winter running! They last a long time - the spout makes the water easy to access and if I don’t bring my vest it’s light and hand sized, making it easy to carry. All in all great functionality. Also their customer service is super friendly and knowledgeable! Rare to have a person on the line AND one who’s friendly.

- 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.

### ⭐⭐⭐⭐ FITLY soft flask
*by A***0 on April 29, 2026*

I was searching around to look for a soft water flask for a chest pack. This 500ml flask was ideal for what I was looking for. It fits snug into the main compartments of the chest pack. I picked a soft flask over a hard bottle because as you drink your water, the shape of the flask shrinks as well, that way it doesn't take a lot of space.
