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

Fits into a small bag which is just what neededTaste a bit rubbery at first but gets better as the newness wears off

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.

This suits me very well for 15km to half marathon runs, outside of the summer months. I bought it for training for my first half marathon (avoiding a chest harness) and was happy with the purchase. Very small and portable. Goes in a pouch intended for a radio transmitter, that I carry on a waist belt. There's a knack to drinking from it (you need to squeeze with your teeth), but the cap locks firmly in place and I haven't had any drips so far. I tend to drink in one go at around the 10km mark, so that the remaining water doesn't slosh around, and this works for me. Better than all the paper cups and plastic bottles at running events, although if it's hot or I am pushing myself, one of these isn't quite enough.

I like the idea of the design as it fits nicely in my running vest and the fact I don't have to carry a bulky waterbottle around is great. I agree to some other reviews about the weird rubbery taste you get and another negative is that there is no lid for the mouthpiece so just in my vest is OK but if I wanted to put it in a coat pocket or a bag I would be worried about how hygienic that would be

Light weight great for portability. Good quality, good value for money.

Energy gels are high fructose which plays havoc with my IBS.Searching for an alternative I found that maple syrup is low fodmap, but I needed a way of carrying enough for a mountain bike race without carrying excess.This is spot on!Easily dismantled for cleaning and convenient for taking a sip from time to time.

The 150ml bottle is very small. You will want double that, or more.

Leaked, product is designed to be transported in a bag or pocket and does not stand up to the job.Leaking from the drinking spout despite not being completely full.

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.

Never leaks, very light and portable.

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

It's really useful but tested like plastic

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!
