Review: Fantastic Addition to My Running Kit - I bought this to help identify my electrolyte flask from my water flask during a long run and it's great! You have to press down firmly to make sure the lid is locked on, but once you do it doesn't leak and stays put! It's roughly the same size as the flasks that came with my hydration vest, so I can keep track of my hydration levels easily. When not in use, I can roll it up for easy storage.
Review: Great for running - Love this! I use this in my running vest and it works really well. Doesn’t leak and is easy to clean. The straw was too long for where I like to wear it high up on my vest but I was easily able to cut it to the perfect length for me and fit the piece back on with no issues.

## Features

- HYDRATION VEST COMPATIBLE: Fits easily in most hydration vests, belts or pack pockets. Provides bounce-free stability and a flexible flask shoulder to prevent chafing.
- COLLAPSIBLE FLASK: Soft material conforms to any pocket, and shrinks as you drink to reduce movement and pack away easily when empty.
- PERFECT FOR AID STATIONS: UltraFlasks are equipped with our SpeedFill Cap designed for quick and easy refilling at aid stations. A side tab pops open the cap in one motion and snaps shut with a click.
- CUSTOMIZABLE CAP: Built for versatility, the UltraFlask comes with a 42mm customizable cap. Choose between straw or bite valve.
- BEYOND LIFETIME WARRANTY: If you experience any issue, we’ll repair or replace the item for free. Whatever it takes to keep your adventure going.

### ⭐⭐⭐⭐⭐ Great little bottle.
*by A***R on February 21, 2025*

I use this for outdoor activity, where a full sized Camelbak would be inconvenient. I shoved this into a fanny pack recently during skiing. I noticed that the fanny pack got a little wet inside. I don't know if the bottle weeps through the cap, or through the drink nozzle. The plastic taste went away after rinsing a couple of times with plain water. I have also learned not to fill this completely to the brim, as closing the lid will always lead to some of that liquid spilling out.
