What is a Hydration Pack?

A Hydration Pack (often called a running vest) is a lightweight backpack designed specifically for running. It fits snugly against the body to prevent bouncing.

Storage Types

1. Bladder (Reservoir): A flexible plastic bag (usually 1.5L - 2L) carried on the back with a hose for hands-free drinking.
2. Soft Flasks: Collapsible bottles stored in front chest pockets for easy access and refilling.

Essential For...

• Trail Running: Where aid stations are miles apart.
• Ultra Marathons: Mandatory gear (jackets, headlamps, food) requires capacity.
• Hot Weather: Carrying 2 liters of water can be a lifesaver.

Tips

Look for a "no-bounce" fit. A loose pack will chafe your skin raw after a few miles.
