The Constrictor was developed with a spinal surgeon from the RCP (Royal College of Physicians) and complies with BS 13407-1999. All the rucksacks have a stress tolerance to exceed 100 kilos pay load.
Designed to protect the spine and distribute weight correctly along the back, reducing wear and problems later in life with the lumbar region of the spine. All the bar-techs machined-in exceed the industry standard and have set new breaking strains – to the point where the rucksacks will not only allow a wounded colleague to be dragged to safety, but will in fact tow a transit van. (Torque on a transit van is 3200nm, our breaking strain is 3411nm)
HYDRO II title here
A top loader with front panel access it offers unique options with our patented back system reduces the amount of energy expended whilst on the move, enhancing the wearer’s performance for longer periods of time.
Available with Jump Lines for airborne insertion, and with our flex panel for JPC compatibility
