Great purchase! on my review.

This has made my life so much easier. I got it to be able to bring water in my Fanny pack when I go to the beach or hiking.It def has a plastic taste for the first few weeks - I got around that by adding about 1/3 a pack of crystal light lemonade mix to my water and then also cleaned it a few times with baking soda.Now I don’t taste any plastic. It seriously is so convenient and great quality. I fill it up and keep it in the fridge ready to go. I’m surprised how the water stays cool for hours…

Pros
  • Nice and lightweight easy to drink from while running and fits in pockets!
Cons
  • The soft flask may not fit securely in hydration packs, causing it to shift or bounce excessively

Perfect size in my review

Given the image I was worried the smallest size was like 50% lid, but not in the least! I wear a leather jacket most times with lots of pocket room and I hate carrying things, so this works great to fill with cold or even some ice and use it to both keep cool under the jacket, but also keep my throat from getting dry.

Pros
  • I use this while on nursing clinicals. I can slip it in my pocket and know I always
Cons
  • The flask may not be suitable for individuals who prefer a firmer, more stable grip on their water bottle while running or hiking

Pros and cons in my review

Pros: 1) I wanted something small that my husband and I could carry in our pockets during our daily 5 mile walks. This is perfect. As you can see in the pic, it is slim enough to put in your back pocket.2) We freeze them with the water inside (leaving room for expansion), so it is extra nice on a hot day to have what is basically an ice pack. The pic shows the water frozen inside. I like holding my bottle against the back of my neck to cool me off, and it speeds up the melting process so that I

Pros
  • Camping & Hiking
Cons
  • The flask may not be suitable for individuals who prefer a more rigid or inflexible water bottle

Update: died & not a fan of the lid/spout

this sweats a great deal if it has been refrigerated or frozen. l found that freezing it is a bit useless for actually drinking due to size & it melts moderately slow/fast if there is nothing in contact with it warming it up. I'm not that fond of the drinking method. The spout is not as easy as applying pressure & "squirting" would be or popping up a spout as would be my personal preference. Other reviewers have mentioned that this particular kind of spout has quite a few benefits, but I just…

Pros
  • Buena
Cons
  • The capacity of the flask may be insufficient for longer runs or hikes

I like the 12 ounce option for my pocket. I wish the bite valve wasn’t as difficult to depress but it does work and is a good option as a back up water source when you go for a walk or run.

Pros
  • STAY LIGHT ON YOUR FEET: FITLY’s collapsible flask is purposely lightweight ensuring your light on your feet and not weighted down by unnecessary bulk. At FITLY, reusability is deeply important to us, and our soft flask is no exception. Enjoy limitless use from our collapsible water bottle that is 100% BPA & PVC-free.
Cons
  • The flask may not be suitable for individuals who prefer to see how much water is left in their bottle at a glance

Perfect for running!

I tried this in the 5oz and realized how much I loved it but decided on longer runs I'd like a bit more water so bought the 8.5oz. Both of these are great and easy to us as a hand held water unlike hard water bottles. I'm an XS woman and the 5oz bottle fits in my legging pockets easily. The 8.5 I found easy to hold then as I used it I could tuck in into my leg pockets. They're also great to tuck into your running bra. I don't notice much of a plastic flavor plus I add a bit of electrolytes so…

Pros
  • Perfect for running, hiking, biking, and other outdoor activities
Cons
  • The flask may be more prone to developing leaks or tears if overstuffed or stretched too far

I really wanted to like this.

I love this product, the 150ml is the perfect size to thow in my pocket for those hour+ runs. The bottle material is good and i love that it collapses.There are some downsides and ways this could be made better. After about three months one of them developed a slit in the mouth piece, probably because you have to bite to get water, and now it will slowly leak in my pocket. If this was made a little more durable, that would be great. But i probably won't get anymore because i don't see…

Pros
  • Ideal for those who like to sip on sports drinks while running or cycling
Cons
  • The flask may not be suitable for individuals who prefer to drink from a straw or bite valve instead of a traditional bottle opening

Great for my daily carry in my laptop sling.

You see those people carrying around giant bottles of water like they live in the surface of the sun? That’s not me. I keep this in my laptop sling. It’s just enough water to quench any thirst. I’m never far away from refilling it, so why carry more in a huge heavy flask?No leaks. Super light. Dig the soft nature of it and how it shrink no’s to nothing as it empties.

Pros
  • Makes it easy to stay hydrated while on the go
Cons
  • The flask may not be as stable or easy to grip as traditional water bottles when using gloves or mittens

Perfect for running- lil tricky to clean

Perfect size for running, however it has a tip that you have to apply tension to clean so a little tricky to get soap out of Thanks for attention!

Pros
  • Shrinkable design makes it easy to store when not in use
Cons
  • The flask may not be as easy to drink from without removing the hydration pack completely

Revainrating 2 out of 5

Not durable on my review.

Pinholes developed in the mouth piece and will leak slightly. I was not biting on the mouth piece hard at all. I'm going to order another Hydrapak stow that is better quality than this thing. Before it started leaking it worked great though.

Pros
  • HYDRATION ON THE MOVE: Our collapsible water bottle is a compact and eco-friendly way to stay hydrated on the move! The soft water bottle is the perfect hydration tool for active individuals. Our soft flasks shrink as you drink, taking up minimal space and won’t slosh around, making it perfect for runners and vigorous activities.
Cons
  • The flask may not be able to withstand harsh outdoor conditions, such as extreme heat or cold

Works great for my opinion

Fits in your purse, as long as it's not tiny. Sometimes I need to take a pill and there is no water available. This is great for that.

Pros
  • Perfect for use during races, marathons, or other fitness events
Cons
  • The flask may not be as easy to fill or drink from if wearing gloves or mittens

Hands Free Fuel on the Bike

Great gel container for cycling. I use the 5 ounce for group rides and races when I need fuel without stopping or causing a safety issue for those around me. Grab from the pocket, bite, suck. Sometimes I even hold it with just my teeth and drink until a hand is free to put it back in my jersey pocket. Two gels and water mixed up in advance of the ride works great

Pros
  • Less expensive and more eco-friendly than disposable plastic water bottles
Cons
  • The flask may not be suitable for individuals who prefer a water bottle with a built-in handle or strap for easier carrying

Great for mid distance runs

Great for mid distance runs when a full hydration pack is overkill. I take one of these soft flasks in my running belt. Quick, convenient, and effective.

Pros
  • Convenient design makes it a great gift for athletes or fitness enthusiasts
Cons
  • The soft material of the flask may make it more difficult to control the flow rate of water while drinking

Easy to carry, doesn't "slosh "

A friend recommended this to me, and it's just what I was looking for. I like to hand-carry on medium-distance runs. The bite valve gives easy access, which is a plus on long winter runs where I don't want to get my gloves wet or fumble with a pop-top. The flask shrinks as I drink so there's no sloshing of water, and the shape and size make it easy to carry out on the trails. Dishwasher safe is an added plus. Thinking about getting the next size up for my longer runs.

Pros
  • Easy to clean with minimal effort
Cons
  • The flask may be more prone to developing a sticky or tacky feeling over time if exposed to high humidity or moisture

Convenient size but strong plastic taste

I liked the size and easy to use nozzle to drink but it has a strong plastic taste. I’ve washed it with soap and a scrubber on the inside multiple times, but it’s still just a little plasticy tasting

Pros
  • Lovely little thing!
Cons
  • The soft material of the flask may be more susceptible to punctures or tears than traditional water bottles

Understated and light weight

Does the job. It’s light and easy to carry while on a run. Had a little rubbery taste at first at the spout, but it goes away eventually

Pros
  • Can be easily carried in your pocket or gear bag
Cons
  • The flask may not be as versatile for use in multiple outdoor activities as traditional water bottles

No leaking good for me

I bought it as an easy way to carry a little extra water on long cycling rides. Fits in my jersey pocket with no problem and did not leak for me.

Pros
  • Fits easily into your gym bag or hydration backpack
Cons
  • The flask may not be suitable for individuals who prefer to mix supplements or other additives into their water while on the move

Perfect size! good for me

I use inhalers that make my mouth really dry, so having a very small amount of water in my pocket during a run is essential. This tiny little ‘flask’ is great! My only concern is that it can be tough to get the lid open at times, and it seems like putting a lot of pressure on the top of the flask while trying to turn the lid is going to rip the material and cause a leak. So far that hasn’t happened, but it does bother me. There is t a good place to grab while turning the lid, other than the…

Pros
  • Flattens as you drink, making it easy to store in small spaces
Cons
  • The flask may be more prone to collecting dirt, dust, or debris due to the soft material

Works great - a bit costly

Bought this to have some water on me for when I walk the dog (who is in way better shape than I), and needed something small, not heavy, no leaking. It works perfectly - does not leak, no odd taste, and the bite valve is high quality. My only comment is that the price is high for getting just one of these; I would think two for this price would be more reasonable. Regardless, I'm glad I got it and it works great for my purposes.

Pros
  • Perfect for those who prefer a minimalist approach to hydration
Cons
  • The flask may be more prone to developing a funky taste or smell over time if not used frequently

Perfect for running !

This flask works perfectly - I use them in regular training runs & during races - never leak and don’t mold or hold onto flavors in the silicone ! They did stain but I don’t care so long as they work properly ! These are pricey for just one 5 oz flask . so I will keep looking for a two pack elsewhere . For now though , this is the best running flask Or bottle Ive tried & I have tried a lot !

Pros
  • Can hold up to 12oz of water or sports drink, providing you with a sufficient amount of hydration
Cons
  • The flask may be more prone to developing discoloration or staining over time
