Parachute straps, straps at both ends, are used to fix the balance of the parachute. Because of the strength and direction of falling, if the body position is not adjusted before opening the umbrella, the belt can hold the parachutist after opening the umbrella in an emergency. If it's too tight. It will over-squeeze the internal organs, lead to body cavity bleeding and damage the internal organs. The splicing of the two ends is convenient for the parachutist to untie the umbrella belt quickly. And prevent the parachute from getting out of difficulty. Something happened. Thank you for your adoption.
