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

This is a great way to carry water while jogging. Bringing a water bottle feels clunky especially if you are running and not close to your home or car to get a sip. This soft flask is perfect for my runs and fits easily into my pouch. Since it is soft and collapsible it doesn't bang against my body hard while jogging. It's also great if you don't want a bag or pouch and just run while holding it. It's now the only water bottle I use while taking a jog. I've been using this bottle for months and really do like it very much.

Absolutely love this soft flask making it easy to pack. No leaks and holds a good amount of liquids. Good quality and recommended!

This thing was great for running and bringing water in a small bag or coat pocket. However, be mindful that it is not the most durable material due to its lightweight - mine has a whole after a few months. I still recommend it, but be careful about keeping other things in the same pocket that might puncture it.

Perfect for running or hiking. If wearing a running vest, it flattens perfectly and i dont notice it shaking or being jolted.

I really like the concept but I've had this for a year and I've used it only during summer months, so a dozen times at most. I can't get the water to be tasteless - the rubber taste stays no matter what. Every sip I've ever taken out of this thing tastes like rubber/or what ever chemicals it's made of.

A great little solution to running hydration. I purchased the 8.5oz option which fits well in mesh shorts over the course of my runs. When fill, the weight can be enough to bounce around, but after a few swigs it fits perfectly in my pocket and is almost unnoticed when running. Easy to use with the nozzle requiring bite force to activate so you will not have to worry about this leaking in your pocket. Great quality for it's price and so far I have not had any issues related to leaks or tears after hours of heavy use. 8.5oz is likely the largest that is pocket friendly when running.

Bought this for a ski trip to keep on my - super convenient to have and I am so glad I did because I am always super thirsty when skiing and this got me through. Didnt leak as long as I made sure the top was pushed down all the way.

Came with a puncture hole in it.. Filled it with water, water streamed out of the puncture hole. Total waste. Nice concept.. Needs to be a much higher quality product.

Bei jeder Wanderung und auch Konzerten dabei! Kein Becherpfand mehr!

La taille correspond à les attentes

If you are thinking of buying, do it!! I have just done a 15 mile walk with two of these and they were brilliant. Didn’t spill at all, easy to handle and nice to drink out of. Weirdly kept cool for quite a long time considering the material. Definitely would buy again

Never leaks, very light and portable.

Compact and fits very well in Nike running belt. A must if you're a jogger.
