ABSTRACT:
A support belt has an intermediate perforated foam layer with confronting unperforated fabric layers laminated on the inner and outer surfaces of the foam layer. Through-holes in the foam layer are trapezoid shaped and arranged and oriented in a circumferential grid pattern to provide ventilation, perspiration drainage, strength and stiffness. A high strength strap with a buckle encircles the lamination to secure the belt around a user's waist.
