FITLY Soft Flask Running Water Bottle - Collapsible Hydration Flask

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 sizedCons: slightly plastic smell (dissipated quickly for me)Bottom line: great way to supplement water on a running course with water already available.

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.

I agree with lots of the positives for this flask. One surprise I wish I had been aware of before I bought it is that it doesn’t have a cap to cover the part that you drink out of. The opening is exposed, which means I’m not able to put it in my purse without risking it getting debris and germs on it. For that reason, I am returning it to get a flask that has a cap. Hope that helps!

This is perfect. Flexible and easy to fit in a pocket for skiing or long walks without the bulk of a water bottle. Didn’t leak. Very pleased.

Leaks everywhere.I bought this to bring to an amusement park for my 3 1/2 year-old and I was gonna keep it in my fanny pack, as soon as pressure is applied anywhere to it at all it leaks, so it did not work for us and I ended up throwing it away.

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...

I have been searching for a bottle to carry with me on short runs for a loooong time. I don’t like to carry things in my hand so my only option seemed to be the belts which carry the bottles. I have one that I love for long runs which has a small bottle on each side of the belt and one I recently purchased which only has one bottle carrier. But still it felt like someone needed to design something better. Well...someone did!!! This small bottle fits into my side pocket and I don’t even notice it while running. There is no fiddling with caps or pushing or pulling....it took me a minute to realize you just squeeze the tip with your teeth and just like that the water comes out. When I read the reviews I thought I would not like the squeezing part and was concerned about the quality of the tip and how long it would last? Surprisingly it’s true what other reviewers wrote, it really is better quality than expected. I purposely waited to write this review so that I have enough time to use the bottle first. There is no swooshing sound of water either. I also love the fact that I can drink while running with ease. Perfect size for 3-5 miles! Just buy it.after using the bottle enough times and

I use this as one of my gel flasks for cycling. Particularly when rides go long and I need to carry some extra calories, a gel flask works great. Three gels and a bit of water are my standard mix for a flask this size, and the Fitly 150 worked wonderfully.Of particular note, the bite valve works great. It takes a bit of a bite to open, plus either some squeezing of the flask with the hand or suction like using a straw. No waste, no drips, immediately closes. That is a great benefit over the standard push/pull type lids on many flasks, where liquid (possibly very sticky liquid if using gels) can leak out. Also, I have a habit with the other lids of catching my tongue in the nozzle; not a problem with the Fitly.There was no detectable plastic odor or taste, though I did give it a quick wash before using.I was a bit worried about the soft-shell design, whether I would have to squeeze the gel out like a toothpaste tube and maybe not be able to get to all my sweet, delicious calories. It really wasn't an issue at all. The walls of the Fitly are actually so flexible that, when you want the last bit of liquid or gel, you can just bite and suction like a straw and the walls of the flask will readily collapse and let you get all the liquid out.

Comoda e resistente. Ottima anche in viaggio

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!

Hay que presionar con los dientes la boquilla de goma para beber... No lo explican en la descripción del producto, del resto bien

La usé para geles energéticos y lo lleve conmigo en el mar. Funcionó perfectamente, no se derramó el gel ni tampoco entró agua salada.

This running portable water bottle is excellent! It’s lightweight, easy to carry, and fits comfortably in my hand while I run. The design makes it simple to take quick sips without slowing down, and it doesn’t leak at all, even during longer runs.I really like how compact it is—perfect for workouts, jogging, or walking. The material feels durable and high-quality, and it’s easy to clean after use. It keeps me hydrated without being bulky or uncomfortable.Overall, this water bottle is a must-have for runners and anyone on the go. Super convenient, reliable, and well-designed. Highly recommended! 🏃‍♂️💧⭐
