Fly Racing - Fly H4 Harness Pack

The H4 is a high performance, 85 ounce (2.5 Liter), hydration system with additional storage capacity.  This storage Based on an ultra light hydration harness this design gives a flexible and stable fit on the upper body where the liquid container and cargo are fixed tight on the back. This prevents the “bumping tank” feel riders get from backpacks that were designed for walking, not riding. The ergonomic fit of the harness angle allows full freedom of  body movements, without impairing safety and comfort, and the absorption of oxygen of the muscles of the upper body and arms. The buckles on the one size harness permits adjustability, facilitating the adjustment to different body sizes and shapes.

  • Holds 85 ounces (2.5 liters) of fluid
  • 5 Liter total cargo space in three separate zippered pockets
  • Aluminized insulation helps keep fluid cool
  • Exclusive, drip-free, bite valve with cover

Comments about Fly Racing - Fly H4 Harness Pack:

The pack is a good size for off-road riding. Good, appropriate-sized pockets. My real complaint is just that it feels like cheap fabric for a $100 hydro pack. No tears or signs of wear yet though in 15hrs of use. Maybe I should be happy is so lightweight?
