ABSTRACT:
A protective liner custom fitted by low pressure fluid injection over a wearer's anatomy, by permeation of select areas of porous padding, surrounding areas of nonporous padding, with an impervious membrane occluding portions of the porous padding to control fluid resin penetration, and with scarfed abuttment of padding for gradual softness variation; including a method by which a pair of liners are simultaneously injected with fluid resin while the wearer's anatomy is in place, for hardening of the fluid resin and of the permeated padding.
