Lifesaver hydrocarry II Unique Features


The LIFESAVER Dualpump™ offers soldiers the significant tactical advantage of being able to fill the LIFESAVER hydrocarry II UF from any water source, without having to remove it from their back. This speeds up the time taken in obtaining water and reduces the vulnerability of the soldier to enemy interdiction.


Incorporated within the Bulldog bite valve is a quick turn spray valve which provides a cooling mist of sterile water. In hot arid conditions this additional feature which can be directed almost anywhere is a great way of cooling yourself and others down. 


Pressurising the LIFESAVER hydrocarry II UF is simple. Pumping the Dualpump a few times is all it takes to pressurise the system. The ruggedized Dualpump is designed to be easily stowed away in a pocket or pouch when not being used.


The LIFESAVER hydrocarry II makes efficient use of the 85% of previously redundant space found  around and below the back protector pad in a soldier's day sack. The LIFESAVER hydrocarry II takes up less than 6% of the internal volume of a day sack and sits parallel with the users' spine centralising the weight. 


The revolutionary single-action Bulldog™ bite valve prevents leaks and drips traditionally associated with conventional bite valves without the requirement for an additional shut off valve. Because the hydration pack is pressurised it is easier for the soldier to drink water without expending significant effort, thus improving hydration and alertness.


LIFESAVER hydrocarry II UF incorporates the latest in Chillwick™ technology which, by using the principles of evaporation, draws heat from the water in the drinking tube, delivering cooler water to the soldier. It does this by absorbing water through the outer sheathing of the drinking tube where it is held by the unique Chillwick gel. This water then slowly evaporates from the gel drawing heat away from the drinking water, through the thermally conductive plastic and away to atmosphere. Chillwick™ technology is also incorporated into the fabric of the hydration pack helping to keep the water cooler. Coming soon!
