WHAT’S AMAZING This is the slim king of hydration backpacks that carries a big tanker of hydration for the extreme races. The Outlander™ 4L 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 NDM™ 4-point harness system that almost glues the pack on your back and makes it 100% bounce free in action. You’ll get access to your phone, your credit card and some energy bars inside the external media pocket. WHAT MIGHT BE LESS AMAZING Having access to 3.0 liters of water might fill you up to the edge and make you go and empty “your own bladder” behind the nearest bush. But if that will ever happen - you know you’re not dehydrated. Which is good!
