About this item
- Insulated Bladder Compartment - Made of Mylar, the insulated compartment reflects and traps temperatures to help keep fluids hot or cold.
- ErgoFit - The human body is intricate and detailed, a complex system. Our packs are designed with the same level of detail, supporting precise movement, contact, and weight distribution. This ensures that the biomechanics of the body are never inhibited.
- On-the-go Pockets and Compatible Bottles: Featuring 8 on-the-go pockets, there are 2 zippered shoulder pockets, a dual 4-way stretch mesh pocket, a pair of stretch mesh pockets (one of which is zippered and suitable for carrying a large cell phone), a zippered side pocket, and a magnetically closed side pocket. UltraFlask, Formula 250, Human 20 oz 2.0, or Collapsible Bottle (NOT INCLUDED)
- MAX02 Sternum - The Max02 Sternum is a shock cord securing system that helps create a comfortable & natural breathing pattern while at the same time keeping the pack secure. The shock cord allows for stretch outward and 100% rebound which keeps the pack snug against your body empty or fully loaded with no restriction of movement.
- Reinforced Main Back Compartment - The main back compartment has been reinforced at the stress points with XT fabric which contains stronger than steel ripstop fibers. This pack includes a 2-liter reservoir that fits into the removable insulated bladder compartment
