## Description

desertcart.com : Azarxis Soft Flask Collapsible TPU Running Water Bottles Handheld BPA-Free 250ml 350ml 500ml 600ml for Hydration Vest Pack Trail Hiking Cycling Climbing (500ml / 16.9oz with Speed Straw - 2 Pack) : Sports & Outdoors

Review: Good runner's bottle! - The insulated jacket comes off easily for cleaning. The bottle itself is more of a "bladder" and collapses flat when not full. A real lifesaver for me because I have vocal cord dysfunction, and a sip of slightly salted water while running will keep the throat open for breathing. Good price, nice features like reflective patterns in the jacket, a hand strap, and a second zippered pouch for light belongings.
Review: Perfect for almost evey run or hike - Bought these to run my 108K ultra, and they worked great, easy to fill, and lightweight. I've used them on 20k, 50k, and 100k runs, as well as all-day hikes, and they are great. I like them because they have twice the capacity of my stock bottles in my running pack. They are tall enough to drink while still in the pack and easy to pull out for a quick refill at the aid stations or in the cool mountain streams. So far so good.

### ⭐⭐⭐⭐⭐ Good runner's bottle!
*by S***O on June 3, 2024*

The insulated jacket comes off easily for cleaning. The bottle itself is more of a "bladder" and collapses flat when not full.

Good price, nice features like reflective patterns in the jacket, a hand strap, and a second zippered pouch for light belongings.

### ⭐⭐⭐⭐⭐ Perfect for almost evey run or hike

### ⭐⭐⭐⭐ Pretty darn good
*by A***Y on October 24, 2025*

Super handy my ONLY wish is that the zipper for the bottle compartment were longer so a full bottle could fit in. It’s a bit hard to squeeze a bottle and an iPhone into but has worked fine for me, and holds gels and fuel great when my phone is in a pocket.
