The Blackhawk Ultralight 3 Day Assault Backpack is a mid-sized pack that won't slow you down in the field. It is made from light, rugged nylon, giving it the durability it needs to survive in the harshest outdoor conditions. Its large, accessible main compartment is secured with silent YKK zippers, and includes five internal tie-downs for securing your equipment in place. It is compatible with Blackhawk hydration gear, and can accommodate a reservoir up to 100 ounces. The front pocket and map pocket provide additional storage space, and the four external compression straps make it easy to lower the bag's profile when only partially filled. S.T.R.I.K.E. webbing on the outer surface supports pouches and accessories, making the design extremely modular. The backpack features a pair of padded shoulder straps and a removable waist belt for effective, comfortable load distribution.
