FivePercentBack.org was created by Hydro Flask in 2009. Hydro Flask stands apart in their belief that great flasks and great causes can go hand-in-hand. They are strong believers in taking care of each other and the environment in which we live. Therefore, when Hydro Flask began in 2009, FivePercentBack.org started as well. Through FivePercentBack.org, Hydro Flask offers you an opportunity to give back to the greater community by choosing a charity to donate five percent of the net profit of your Hydro Flask purchase.
