Modern Hydration
Comes From The Past

It all started in 1979 when Bryce was unable to find a pack that allowed him to maximize his performance, so he decided to make one himself using his grandmother's sewing machine.

Since then, Bryce launched the very first hydration company, invented hydration belts, packs, handhelds, vests, produced the first screw top water bottle for runners, and introduced many other industry firsts. His innovation came from need, and it continues out of the need to perform better.

Today, almost all hydration products are iterations of Bryce's original designs and he continues to drive the industry forward, setting UltrAspire apart from all other brands.
