## Description

desertcart.com : 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) : Sports & Outdoors

Review: Great bottles, especially for traveling. - 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.
Review: great soft flasks - 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!

## Features

- Safety Promise: Made of food-grade TPU material, 100% BPA & PVC Free, the soft water bottle is tasteless and eco-friendly.
- Space Saving: The soft water flask is compact and built for a long life for durable use. The running flask stands upright when it's full and shrinks in the min volume when empty, no burden for sports.

## Questions & Answers

**Q: I want to carry this in place of a plastic deer park water bottles for a running belt. Will this swap work?**
A: Probably not. This bottle is completely collapsible, and when the water level gets low, the straws cause the bottle to sag.

**Q: Does this start to collapse when you drink? I want to omit hearing the water sloshing sound when I run?**
A: Yes, it is. You gonna listen anithing. It is perfect for running

**Q: Do all of the sizes and packs of 2 come with the straw?**
A: No. The 250ml and 500ml did not come with the straw.

**Q: Will this work with osprey enduro 6?**
A: Sorry, we can not judge if the bottles can work with the osprey enduro 6. We suggest that you can contact with Osprey to ask about the size of the bottles pocket..

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.

### ⭐⭐⭐⭐⭐ great soft flasks

### ⭐⭐⭐⭐⭐ Nice product
*by A***G on November 2, 2022*

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.
