MIL-W-25361 Type I, II, III, IV, V, VI Strap and ribbon

The MIL-W-25361 strap is flat, smooth, and extremely durable. It is used in military aircraft seats to secure the pilot in all possible flight scenarios.
Its moderate elasticity allows it to absorb shocks, sudden acceleration, or ejection; its smooth surface facilitates sliding by reducing friction to prevent burns.
This strap is located in the cockpit, so it must comply with fire, smoke, and toxicity standards through specific treatments.
