Sizing & fitting information regarding the back protector integrated onto the
System
Back protectors are certified to EN 1621-2:2014 are sized by 'Waist to Shoulder length,' as
this gives the best representation of back length. Waist-to-shoulder length is the length

function of the System. Notwithstanding one single size back protector cannot fit all body
