This pack comes with 2 UltraFlask 550 Hybrid Bottles. The bottles are simple and intuitive, and the holsters provide easy access on the go.

Both holsters are insulated to keep fluids cooler for longer. The holsters are designed with a mechanical locking system to prevent launching but still allow easy access. The bottle sits securely in the belt with the weight close to the body proving the most stable 2-bottle pack on the market. In addition to hydration holsters, this pack is equipped with a 4-way stretch mesh zippered pocket to hold items you may need for later. For items you need more frequently, each holster also has a quick stash pocket for rapid access.
