This bag was designed to meet the requirement of diving and submarine lockouts. It provides protection via DUI’s 3-bag concept. The waterproof bag is nylon trilaminate. A 1,000-denier Cordura stuff sack is included to store the equipment in to protect the inside of the waterproof bag. The outer Cordura bag takes most of the abuse. All of the straps are sewn to this outer bag so the least amount of stress is placed on the waterproof bag. This bag is ideal for water and land use. An easy to use oral in ator delivers optimal buoyancy control.
DUI also manufactures a bag that is larger designed with the exact features of the Amphibious Rucksack. It was originally designed to hold the Para Rescue Teams (PJ) full medical rucksack with the frame attached. This enabled them to jump into the water with the medical rucksack and later removed.
