The main compartment of this water backpack is roomy enough to carry water bladder, iPad and lunch box. The Molle system allows you to attach other gears to the pack. Adjustable shoulder straps, chest straps and waistbands can make the backpack more suitable for your body shape and reduce the swaying of the backpack during hiking. The soft, breathable mesh pad on the back keeps your back cool and dry. This tactical hydration pack is the best choice for short trips, running, cycling, and hiking, skiing, camping, and hunting. The net price is not included a water bladder. Your logo is welcome.
