In coordination with our connections in South Africa we developed this new rescue strop featuring an extra "Hypothermia" strap to stabilize the knees of the patient in a sitting position. In the water it is very easy for the rescue man to adjust the yellow strap to the right length to lift the knees to the right level.
The strop still features the Triple-S system consisting of 2 red handles for the patient to hold on to and securing himself at the same time.
