The Billingham Hadley Small comes in two materials, the traditional canvas and the newer FibreNyte. Billingham indicates that:

"The material is purely synthetic, it has excellent abrasion resistance while remaining supple.We've found a solution that is softer than other man made fabric...FibreNyte is a high performance, super durable fabric which is bonded to a polyester lining using Billingham StormBlock butyl rubber and weighs 10% less than our traditional canvas...FibreNyte is more colourfast because the dyes can be bonded to the material more easily. The black stays black and the Khaki stays Khaki."

Could someone with experience with the FibreNyte (and maybe with the canvas, too) provide some guidance on quality, feel, and looks?
