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.

Just picked up a pair of the 500ml/17oz soft flasks. Both hold water - no leaking and fit great into my running pack (Nathan vapor air). The water tasted like...water out of the flask - very little synthetic aftertaste that you get from some. The bite valve works well and flow was good for getting water while running. I am yet to take them on a long trek, but will update review after. Pro tip: small opening so they need to find a breezy spot to dry out - but doesn't seem to be a problem!

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.

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.

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 use soft bottle for spare water on hikes. It’s lighter than carry an extra bottle. Only wish I could attach a Sawyer Mini but the opening and treads are not compatible. Also wish there was a compatible cap. Other than that, perfect lightweight option to nalgean or water bottles and doesn’t have a bad taste. Easy to clean. Only used one of the 2 pack and it’s seen several aggressive trips. Seems to be holding up. No leaks or rips/tears.

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.

These are fine bottles they seem like they will last a good while. I do have a few gripes. First being that the mouth of the bottle is very small so I have to use a funnel to get any sort of mixes down into the bottle itself. Second they don't stay in place in my vest Salomon Sense Ultra 8. Because of the narrow caps the elastic that holds in the regular salomon soft flasks does not hold it up. It will be fine when they are full but as soon as you start emptying your bottles they will sink down the vest which is super annoying. The price made these attractive but I don't think I will be able to rely on them any longer.

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。

Great and very durable. Used these for many festivals when sneaking in alcohol. One has discoloured slightly with whiskey but we've had 0 issues otherwise. Deffo recommend

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.
