Ultimate Direction Hydration Tagged "Hydration"

OUR STORY - UDXXX SINCE 1985

The new 4.0 Signature Vests have been taken to a new level - completely redesigned from the ground up.

The 4.0 Signature Vests now feature Comfort-Cinch technology and lighter weight for the ultimate combination of comfort and performance.

The Comfort Cinch is here to change the game of personalized fit.

The Comfort Cinch system takes technical design to a new level.

The lateral adjustment happens over the small of your back instead of on your sides, for greater comfort

and improved sizing and stability. Comfort-Cinch allows the vest to fit like your favorite shirt.

Technical materials provide performance and comfort

Technical materials for technical terrain. Knit Mono Mesh ensures 4.0 vests stay in place. No movement, no chafing, full comfort.

Athlete-designed details work for everyone

Improved trekking pole holders that don’t bounce, and larger sized phones are accessible up front.

In 1985 Ultimate Direction invented the entire category of hydration packs. We created the first waist pack for carrying bottles, a few years later made the first pack/strap to carry a water bottle in your hand, and have made many other innovations that define what a hydration pack is today.

30 years later we remain a market leader, having created and popularized the "vest" concept for carrying water. We introduced the very first women's-specific line of hydration packs and have brought the classics of the past into the technical future with award-winning gear such as our Fastpack and Ultra Jacket.

Our Signature Series Collection are designed by athletes for athletes, and the Jenny Collection was designed by female athletes for aspiring and elite females alike. Some of the best runners in the world thought long and hard about what works the best, and the result is absolutely great gear from Ultimate Direction.
