What is most difficult restraint to escape from?

The most difficult restraint to escape from is often considered to be the straitjacket. Designed to prevent movement of the arms and upper body, it restricts the wearer’s ability to use their hands effectively, making self-release nearly impossible without assistance. Additionally, the added pressure on the body can induce panic, complicating escape efforts further. Other restraints, like handcuffs or leg irons, may be more easily manipulated or picked, whereas straitjackets are specifically crafted to ensure confinement.
