Outlander 4 Backpack USWE This is the slim king of hydration backpacks that carries a big tanker of hydration for the extreme races. The OUTLANDER 4 is geared-up with a 3.0 liter Elite hydration bladder with a Slide-Seal top for easier filling. The pack is designed with our award winning No Dancing MonkeyTM 4-point harness system that almost glues the pack on your back and makes it 100% bounce free in action. To keep you hydrated and focused while on the move, we picked a large and durable 3,0L / 100 oz Elite hydration bladder for the to go inside the pack, with a big slide opening at the top for quick filling of ice and water. And after the race, the bladder is fully reversible for easy cleaning and drying. The Hydraflex drinking tube sits securely close at hand with the tube clips. The pack is compatible with the hands-free kit (sold separately) if you want to attach your tube to your helmet.
