In 1985 Ultimate Direction invented the entire category of hydration packs. We designed the first waist pack designed to carry bottles, a few years later created the first pack/strap to carry a water bottle in your hand, and made numerous other innovations that helped define what a hydration pack is today.
Our products are Designed by Athletes for Athletes. Some of the best runners in the world thought long and hard about what works the best, and the result is the amazing features you see today. Our women's collection was designed by women, which is why it looks, feels, and fits completely different.
