Abstract
This invention relates to a cast liner that provides improved comfort over prior known cast liners. The cast liner provides several layers of material having functions which functionally complement one another. The inner layer comprises a soft highly breathable material with a first layer comprising a high wicking nonwoven material overlying the inner layer and a second layer comprising a stitch bond fabric which is relatively stiff but open and compressible to support the body through the underlying inner and first layers.
