Christopher Siepmannwrote a review of CamelBak Dirt Series Podium Chill 21oz Bottle on April 30, 2018
Since mountain biking throws so much dirt around, these water bottles are perfect. Its super simple to flip the cap off while riding, but it keeps your bottle top nice and clean. The chill is also great to keep your drink warmer throughout the ride. Obviously it isn't YETI metal waterbottle status (but is way lighter weight!).
