The FS-1 Mojave design allows you to add Coaxsher accessories and also Coaxsher pack modules later giving you the freedom to configure the pack to your exact needs. When you purchase the FS-1 Mojave you get the main pack harness, water reservoir case that holds up to a 3.0L water reservoir (water reservoir sold separately), and the new generation fire shelter case w/ glove compartment. The fire shelter case attaches to the main pack harness with quick-release buckles but also comes with alice clips to attach to the sides of the hip-belt for engine ops. The ergonomic suspension harness provides all-day comfort with its high-quality padding, aluminum stays, and our new patent pending D.A.S. Dual Action Stabilizer system.
