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

I’ve bought other bladders from this company before, which have lasted for well over a year (still going) and recommend them to friends. They’re really light weight and are great to fit in your pocket when snowboarding or in a small bag when out and about. I’ve never had any issues with leaking and although initial they do have a funny taste (not too bad), that quickly goes. This one seems much the same - bought for running as I hate carrying part empty bottles - these reduce in size as you drink, so there is never air in them. The holder seems weak made and fits well. I love the pocket at the front - great for keys and a bank card for emergencies.

This fits perfectly in my pocket and doesn't leak (you have to kind of bite down for the water to come out) Took one star off as it doesn't have cap/cover so all the fluff from inside my pocket stuck to the mouthpiece.

I was impressed with how it felt on a run, fit my hand well (glove size 9) and the extra pocket is great for small things like keys and inhalers, or Gu.(better than things jingling in a pocket). Using is great and it's easy to take occasional sips without breaking a stride. Reflectors on the straps and side are a nice touch. Doesn't leak or drip. Bit of a funny "new" taste but better with some soapy water and a soak in mild citric acid. I'm sure it'll go with use (edit: it has) Ideal for 5-10k ultras.

Annoying if I shove this fully in my pocket it leaks. And if I leave the top sticking it then the flask slips out. So it’s pretty much useless. Needs a lid

The 350ml soft water bottle is a good size to store in your rucksack. Easy to use, lightweight and didn’t leak. However, whatever I do to remove the rubber smell and taste, does not work. Even if you use a strong tasting squash to dilute, the rubber taste is overpowering. They are not usable, buy something else.

Love this bottle, great when your out running, easy to carry and leak proof, great condition and value for money.

Very handy, run with this regularly. Would be nice if it had a peg like clip so you could clip it to a running belt and switch easily between hand held and belt, but that would be a nice extra. My only down side is that the water you drink from it does have a bit of a plasticky taste to it - not sure if this is common with soft bottles. Not stopped me using it though!

Fantastic concept. Great for putting in a pocket when skiing. Didn’t leak.

I live in Fl, and I run outside. Those two components demand that I hydrate or die. I prefer the land of the living for now, so gimme the H2O. I already had the Fitly minimal pack, just not this particular flask. I originally thought I would have to bite the bullet and get a new pack altogether, but then I found the flask available by itself. I ordered, it arrived, and I have been using it for a couple weeks now. A decent amount of water for daily runs, depending on speed and sun exposure I would say 1-2 hrs. The only hiccup I have noticed is the screw on top with the hose attached can be a little tricky to get on without spilling some water. Other hydration packs have a slide that seals the reservoir; I can see why the screw top here, based on minimalist approach. It is worth the small effort with closing to be able to have a smaller pack to carry.

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.

I have used it for a week and i5 worked great. No leak. It’s so small so I don’t feel it in my pocket. Some reviews complained about the smell. What I did was filling in dark tea, leave it for 8-10 hrs, and then leave it uncapped for 8-10 hrs. Repeat it. Now I don’t smell the plastic anymore.
