From IV Bags to Tactical Gear: The History of Hydration Packs
Hydration packs have become an essential tool for athletes, military personnel, and outdoor adventurers, but their origins stretch back far longer than most people realize. From ancient water-carrying methods to high-tech, hands-free hydration systems, the evolution of hydration packs has been shaped by centuries of necessity, military innovation, and modern science. What started as a simple IV bag strapped to a cyclist’s back has evolved into one of the most efficient ways to stay hydrated on the move.

The Earliest Forms of Portable Hydration
Ancient Civilizations and Water Transport
Long before modern hydration technology, early civilizations relied on creative ways to transport water.
- Ancient Egyptians, Mesopotamians, and Romans used clay vessels and leather pouches to carry water on long journeys.
- Nomadic tribes in desert regions developed camel bladders and hollowed gourds, which were lightweight and naturally insulated to keep water cool.
- Roman soldiers and medieval warriors carried water skins and metal flasks to sustain them during battles and long marches.
Even though these solutions worked, they all had one major flaw—they required frequent handling and slowed movement in critical moments.
The Military Evolution: From Canteens to Hydration Systems
As civilizations developed more advanced militaries, the need for efficient hydration methods became clear.
- 19th Century: Soldiers carried metal canteens, which were often heavy and difficult to access in combat.
- Early 20th Century: Military-issued canteens were made from aluminum, then later plastic, making them lighter but still bulky and inconvenient.
- WWII & Vietnam War: Soldiers started using canvas-covered canteens, which provided some insulation but were still carried externally, requiring frequent stops to drink.
By the 1980s, military strategists recognized a problem: canteens were outdated. Soldiers needed a way to stay hydrated without breaking stride or taking their hands off their weapons. But the breakthrough didn’t come from the battlefield—it came from a cycling race.
The Birth of the Hydration Pack (1989)
The real breakthrough happened in 1989 when Michael Eidson, a cyclist competing in the "Hotter ‘N Hell 100" race in Texas, realized he needed a way to stay hydrated without stopping.
- Eidson’s solution: He took a medical IV bag, filled it with water, and placed it inside a tube sock.
- He then ran a plastic tube over his shoulder, allowing him to drink hands-free while riding.
- This simple, makeshift design was the first version of the modern hydration pack.
Recognizing the potential of this invention, Eidson founded CamelBak, a company that would revolutionize hydration for endurance athletes, military personnel, and tactical operators.
Hydration Packs Enter the Military (1990s-2000s)
While hydration packs gained popularity in cycling and endurance sports, the U.S. military took notice in the 1990s. Soldiers were still using canteens, which were bulky, noisy, and difficult to access during combat.

Why the Military Switched to Hydration Packs:
✔ Hands-free drinking allowed soldiers to stay hydrated without stopping.
✔ Water stayed cooler longer due to insulated reservoirs.
✔ Hydration bladders were quieter than sloshing canteens, improving stealth.
✔ Hydration packs reduced bulk compared to rigid canteens.
By the time the wars in Iraq and Afghanistan began, hydration packs had replaced canteens as standard military gear.
- Tactical hydration packs became mission-critical gear, with brands like CamelBak and SOURCE Tactical leading the way in rugged, battlefield-tested hydration systems.
Modern Hydration Packs: More Than Just Water Carriers
Today’s hydration packs offer far more than just water storage. They incorporate cutting-edge materials and designs to enhance performance in the field.
✔ Insulated Reservoirs – Keeps water cool for extended periods.
✔ Quick-Release Valves – Easy refills without removing the entire bladder.
✔ MOLLE Compatibility – Attach extra pouches or gear for tactical operations.
✔ Built-in Filtration Systems – Purify water on the go for survival situations.
✔ Lightweight and Ergonomic Designs – Reduce fatigue while maximizing efficiency.
Brands like SOURCE Tactical and CamelBak continue to push innovation, making hydration packs tougher, smarter, and more adaptable to different environments.
