Carly Cassidywrote a review of Hydro Flask 21oz Standard Mouth National Park Foundation Water Bottle on August 16, 2019
I bought this for my dad for Father's Day. My favorite childhood memories are of family vacations to National Parks. Hydro Flask makes my favorite bottles, so I was excited to see they partnered with the National Park Foundation on this one. My dad loves it because it keeps water cold for over 24 hours!
