    Love this bottle

    I ordered this bottle to go in my vest. I love it! It fits great and perfect for adding in Electrolytes. It is easy to clean and use as well as very light weight.

    Too tall

    Great quality, but too tall to fit properly in the front pockets of the Gear Vest. The 500mL is what you need if fitting all the way in the pocket is a priority. But the extra fluid is good, so I recommend it if you aren't as OCD as I am.

    Ultra flask

    Love all my products from orange mud. This flask is amazing because as I drink out of it it collapses allowing less bulk while out on longer runs.
