TRIWONDER TPU Soft Folding Water Bottles BPA-Free Collapsible Flask for Hydration Pack - Ideal for Running Hiking Cycling Climbing (500ml/16.9oz - Pack of 2)

Why did you pick this product vs others?: I haven't used these yet (I will next week) but my sister recommended them highly. I do like that I can stuff them in a suitcase while still all rolled up.

These are leak proof, light weight, and fit in the sides of my running bag. I used these on my trek in the Grand Canyon that took about 16 hours. These together hold a liter and you can drink fast without stopping which is awesome. They’re soft and won’t rip no matter how much you abuse them

If this leaks, check for shrink wrap plastic under the silicone sleeve. Check my pics. There was a piece under the sleeve and causing it to not seal. You can gently pull off the end then clear that with tweezers then reassemble. Make sure to push the sleeve on to engage the lip (red outlined area). Good to go now!

I got these to have as extra bottle to carry in my running vest and bike packing frame bag. I wasn't expecting much since they're inexpensive Chinese made, but they're actually pretty good. Most of all I was pleasantly surprised with the bite valve working well. It's no Camelback valve that I prefer, but nobody is as good as them anyways. So it's nice to be able to carry a little extra water without it taking up too much space. I did experience the plastic flavor others have complained about, but it went away after a good washing. And I should have went with the wide mouth version as the opening on this version is too small to easily put ice into. Otherwise I'm happy.

very easy to wash, it is a lie that the water tastes like plastic, you have to wash it first and the bad taste disappears. it is common sense. I recommend the product Hay que lavarlo con agua y jabon por dentro, para que el liquido no tenga sabor a plastico. Es muy comodo de cargarlo en la mano en caso que salgas a correr y facil de usarlo.

Perfect soft flasks to fit in the Aonijie 18L hydration running pack or to use solo and carry. Each flask holds 500 mL beverage which is ideal for about 2.5-5 miles of running depending on intensity. I've used these with hydration electrolyte carbohydrate solution and also just water, and they work easily and efficiently. The bottle does not take much bite force to open the bite valve and get a squirt of liquid, liquid is also ejected with very little squeeze pressure. Wouldn't use any other soft flask for running or exercise! I'll keep coming to Aonijie for my hydration and exercise/trail running needs!

I use these to carry extra water on runs. I can deal with the difficulties of drinking from the nipples and lack of access to clean the interior or the lid, for the reusability of these items and the ability to carry so much water. But I cannot deal with how much the lid on one of the bottles leaks, it goes all over me and wherever I lay my pack down. I tried messaging the company over a defect in another item that I received from them and have yet to hear back from them, therefore I view this as a lost cause right now. I would not recommend buying products from this manufacturer/seller.

I have used these for a few months and so far they seem better and more durable than my Solomon flasks. Solomon is usually awesome for everything, what happened. I'm impressed by these. So the spouts can be pulled off if you're running and biting down on them, that's been my only hang up so far. Why? probably for cleaning reasons, which I'm ok with. If you accidentally bite it off while running, you'll get sprayed with half of your water bottle. you learn fast. Otherwise, I've really liked these and they seem strong!

These bottles are good quality and cant wait to use it

Wie immer schnelle Lieferung in Prime Qualität. Die Verarbeitung der Flask ist gut. Beim ersten öffnen der Flask richt es stark nach Kunststoff. Am besten erst ausspülen dann die Flask mit etwas Spülwasser füllen und über Nacht liegen lassen. Nochmal ausspülen, so sollte ist der K-Stoffgeschmack weitestgehend eliminiert sein. Zur Info, auch Trinkblasen von renommierten hochpreisigen Anbietern können schonmal nach K-Stoff schmecken.

500㎖×2を購入しました。 ランニング用のバックパックに装着してピッタリ収まりました。サイズ、形状、共に扱いやすいです。 質感はしっかりしているので丈夫な感じ。軽くくわえるだけで水分補給しやすいです。 以前のもの（バックパックの付属品）より良いですね。

j’adore les prendre pendant mes voyages à sac à dos Au moins cela ne prend pas de place du tout

Muy buena calidad a un buen precio.
