## Description

Buite 150ML Soft Flask, Portable TPU Soft Flask Running Bottles for Running Vest, Hydration Pack - Ideal for Hiking Cycling Climbing（Gray)

Review: Good size for a very portable flask - This is a great little flak. I got this for snowboarding because I saw others with this kind of water bottle and it's so smart. Your able to carry the bottle in any pocket and it fills down to almost nothing once your done drinking. I had another bottle for running and that one spoiled all over me when I tried to drink from it, so now I carry this flask with me instead when I go running. I like the way the mouth piece works, it's impossible to spoil water on yourself.
Review: Washed clean but still has odd taste - Have washed several times but water still had an odd taste. Good size and handy to use while running.

### ⭐⭐⭐ Washed clean but still has odd taste
*by A***R on 21 September 2025*

Have washed several times but water still had an odd taste. Good size and handy to use while running.

### ⭐⭐⭐⭐⭐ Sweet portable/collapsing water bottle
*by S***G on 1 February 2025*

I travel quite a bit for my work. I have basically a "Mobile Office" in my back pack which has my laptop, a second screen, kindle scribe, battery packs, chargers, etc. etc. etc. I used to also carry a water bottle, but that has now become my blender bottle. I am not a fan of single use plastic water bottles, yet I really don't have any room left to fit in my backpack. Bam! This water bottle comes into play! I don't have one of those athletic chest strap thingies because I'm pretty basic when I go for a jog. This though, I can shove it in a tiny nook when I need to go from place to place, then when I arrive, it's super easy to fill up and it doesn't leak. When I'm done I just smoosh it back into my backpack and I'm ready to go! It's a little bit of a pain to get that little silica gel pack when you first get it, but that's such a minor inconvenience. This thing is sweet and allows me to hydrate while bringing along my mobile "command center" as I have dubbed my set-up.
