This compact strap can be used in conjunction with our #214 Quick Strop to provide support under a victims legs to effect a more horizontal recovery position.  Some rescue units use a double-strop system in cases of suspected mild hypothermia, but at only .34 kilograms this device easily stows in your kit bag until needed.  For use directly on the hoist hook or attached to the equipment hook on your Tri-Sar or Triton harness,  the hypo-strap is identical to the crotch strap in form and function.
