FITLY Soft Flask - Shrink As You Drink Soft Water Bottle for Hydration Pack - Folding Water Bottle Ideal for Running, Hiking, Cycling, Climbing & Rigorous Activity

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.

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!

*Update: adding a star because I was finally able to get contact info for the company & they sent me a new top. You have to contact them through their company website. I love the 5 oz size of these for sticking in easy to reach spots for hiking and xc skiing between bigger water breaks. It's also something I can hand my kids they can easily drink out of and not spill. I have three of these and love them but now two have sprouted holes in the bite valve. That seems pretty fast compared to a normal bite valve - my water bladders have only needed 1 replacement over many years. I'd buy more of these if they sold or offered replacement bite valves or tops. Hoping I can contact the company somehow to request one since I really do like the main design of these.

I use this flask on my long runs. Perfect size and fits easily into my running vest. It’s easy to use while running and does not leak. Love the hot pink color.

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.

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 Soft Flask is perfect for running—lightweight, easy to carry, and shrinks as you drink, so there’s no sloshing. It fits well in my hydration pack and packs away small when empty. Great choice for staying hydrated on the go!

Expert skier who previously used water bladders with tube fed through the backpack for hydration while skiing. On cold days, the tube would freeze to my dismay. Nothing I could do to fix this issue worked. I tried insulated tubing without success. I then started carrying a 500 mL bottle of water each day in my thigh bib pocket which worked in terms of not freezing, although I found the shape of the bottle uncomfortable. I ordered this soft flask at the 400 mL size as I thought it would fit in my pocket and yes, it does. I fill it when I go in for a brief break and it is fine for resort use. Would this work for backcountry? Well, personally 400 mL isn't enough water for me for more than a few hours so I think this will have to stay for resort use. But for what I need, it works perfectly. The reason I gave it 3 rather than 5 stars is the taste of the water... despite filling it initially with hot, soapy water to clean, I still taste would I would best describe as the inside rubber/plastic taste/smell of a pool toy. If you have ever blown up a pool toy, you know what I mean. With time it has been getting better but the taste remains. On the product it is clearly advertised that the product is safe for use with claims of product safety by FDA, but who knows...

Maraton ve orta mesafe koşulları için çok güzel.

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!

Filled it with water and left it on the counter. It leaked. Tried to tighten it up even further, kept leaking. Useless

Después de probar varias marcas y precios, entre ellas las de decathlon, os puedo asegurar que esta pequeña y flexible botellita es cómoda de llevar en bolsillos de mallas o mochilas de Trail. Lo mejor de todo es que el agua NI SABE a plástico, como si me pasaba con las anteriores compradas. Muy recomendable. También he vomitado la de 500 ml.

Storleken var perfekt. Smakar plast när man dricker ur den. Läckte lite då locket är svårt att få på helt rätt
