It all started on a sweltering day at the beach in Hawaii in 2008.

That day, Hydro Flask’s founder had an epiphany that forever changed the water bottle market: Instead of a bland, sweaty, sand-encrusted container of unrefreshing, lukewarm water, the world needed to quench its thirst with a reusable bottle that offered safe drinking and high performance in an attractive design. The result was the first Hydro Flask, incorporating double-wall vacuum insulation, BPA-free materials, food grade stainless steel, a range of fun, durable colors and a charitable arm called 5% Back. And with great quality comes great commitment, so Hydro Flask created its lifetime warranty to stand behind its products.
