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.

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.

FITLY soft flask
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.

Easy to use soft flask for running!
This handheld soft flask is great and easy to carry with me on my runs. Easy to use. Has a slight plastic taste at first but I’ve soaked it in hot soapy water and that has helped. The little pocket on the hand held “carrier” works well to hold my keys and a small snack. Wished I’d found it sooner! Good quality. Easy to use and carry!

Great for 4-5 months until it breaks, also plastic taste after a few hours
This bottle was great for one season. I really liked that it compressed and fit in a pocket when it's empty. The top seal worked well if you made sure it was tight. But.. You could not leave water in it for more than a few hours without it tasting very plasticky. That never really went away, but it was fine if you filled it and drank immediately. The main problem is it sprung a pinhole leak after 5 months of 3x/week low impact use. Then it sprang another, so in the trash it goes.

The Perfect Size Bottle for Extra Water
I don’t like to carry a water bottle when I go on a run. At events and our local track, there are water stops along the course, but I like to have a little water with me so I can hydrate to my thirst. This bottle is absolutely perfect for that need. It fits in my pocket and does not leak and lets me get small boosts of hydration between water stops. It does not hold much, but for me it is perfect for hydration supplementation during a 10k. If this is all the water you have / available, it would not be big enough, but for races where you know there will be water stops offered, this bottle is great. There was a slightly plastic oder when I first got it, but it went away quickly and the water never tasted off. Pros: easy to fill, easy to use while running, great size for extra water, easy to clean, pocket sized Cons: slightly plastic smell (dissipated quickly for me) Bottom line: great way to supplement water on a running course with water already available.

Leaked
I bought this with a waist belt for a 10k. I opened it the morning of the race to use it, but it leaked all over me. It looked like I had peed myself for the entire run, so that was fun for the pictures.

Perfect for Running
These flasks are perfect for running. I carry these in an expandable waste belt and the fit is great. Light weight, convenient and easy to use while running. I usually carry one in cooler weather and two when it gets hot. The size and capacity are perfect.

Ideal for running!
I love using soft water bottles because they don't take up much space. They are lightweight, flexible and collapsable which is ideal for when I go running! And this one fits perfectly into my waist bag :) It's also leakproof and I did not notice any bad taste in my water plus I really like this type of mouthpiece!
