Shimano Unzen 10L

Shimano Unzen 10L

The Shimano Unzen 10L is a rethink of the traditional hydration pack. Its shoulder straps form an X across the chest, securing the load higher and tighter for more comfort on runs and rides (think body armor, not backpack). The goal isn't just stability; a static load saps less energy, because you're not trying to balance it with the small muscles of your back. Also, it's clever: Side access lets you swing the pack around your torso for quick access to tools, spare clothing, and snacks. [$100; bike.shimano.com]
