The RUSH72 2.0 is the largest of 5.11's RUSH line at 55 liters, a full 72-hour bag for extended trips or serious bug-out loads. It expands the RUSH formula, admin organization, laptop and hydration sleeves, wrap-around MOLLE, into a pack that swallows multi-day gear while staying rugged and comfortable under weight. Built from 1050D nylon with self-healing YKK zippers and a padded, adjustable harness, it is engineered for the long haul. When you need one pack that can carry everything for three days, this is 5.11's answer.
