Works exactly as advertised

These flexible water bottles are easy to fill and stay snugged on the running body strap. Highly recommended.

Great water bottle for running!

Water bottle collapses on itself as water is sucked out so no sloshing around while running. Perfect size for adding electrolytes.

Kathleen Pallardy
Best Flask out there!!

Love these flasks! Used them for the Umstead 100 and drank one every hour with electrolytes.

Solid product

Orange Mud hits it out of the park. You do have to be diligent about keeping them clean.

Perfect for electrolyte drinks

This lil guy is perfect for my electrolytes when I run!

Dry mouth, no way

The soft flasks resolved our issue of having bulky water bottles that take up space when empty. We could stuff them in a pocket when empty.

Works well, easy to clean.

Soft water bottle.

I have been using the bottle on every run. I love taking occasional small sips. Cheaper than the running store and love the pliability.

Awesome

I've purchased two of these water bottles and they work excellent. I need a lot of water for my long runs so I fill up the hydration pack along with two of these with electrolytes.
