FITLYSoft Flask 3 Pack - 5 oz (150 ml), 8.5oz (250ml), & 13.5oz (400ml) - Shrink As You Drink Soft Water Bottle for Hydration Pack - Folding Water Bottle for Running & Hiking

Very happy with this product

Very good but it doesn't have a cap to make it hygienic if put in a pocket or bag. A big problem, I wonder how they missed having one.

Impossible to clean the mouth piece properly, used twice with gels and found mould growing inside the bite valve despite my best efforts at cleaning. Strong plastic taste/odour to water initially.

Unusable flask as although it functions fine I cannot remove the horrible taste the water takes on from the product used to manufacture. I've tried washing it out, putting bicarbonate of soda to clean, soaking it. Nothing has worked. Would not recommend, I've wasted my money.

For walks around the neighborhood or short hikes, I hate taking a bulky waterbottle. I don't like having a backpack, fanny pack, or crossbody for sensory reasons, so having a small, lightweight way to carry some hydration was on my list of 'things to find.' Well, I found it! The selection of sizes allows me to take just what i need for that day's particular 'adventure'. Once I have finished the water, it is like I am carrying hardly anthing at all (unlike a water bottle). It easily fits in my pocket full and empty. Drinking from them took a few tries to get used to you, you do indeed have to bite as instructed which feels like a no-no based on past mouthpieces that would tear. These hold up to the biting. I also did a few vinegar rinses to be sure there was no silicone flavor, and that worked well. The mouthpiece does not give or leave a silicone or plastic flavor either, which was important to me. I love these!

these collapsable water bottles are perfect for the ski slopes. My kids always take one to Nordic ski practice. They are lightweight and easy to use when wearing gloves.

They got the job done, though they made the water taste very strongly of rubber after multiple washes with soap. The top part is a good design to prevent spilling, but horrible for trying to drink from it. It’s better to just unscrew the top altogether unless you want water everywhere.

Les flasques gardent un très fort gout du plastique malgré plusieurs lavage, l'une d'entre a moisi et n'a pas été récupérable malgré la javel.De plus le bouchon non protégé n'est pas très hygiénique quand on veut transporter les flasques dans le sac de sport ça traîne partout et ensuite on le met à la bouche ... bof pas vraiment convaincuElles ont par contre l'air solides d'ou la 2eme étoile

Very easy to use. Easy to clean. Easy to pack as well. I do recommend them for runners.
