A new material to the market, it's as close to Colobus monkey than i've ever seen, the difference with this compared with whats already available is that on the piece you recieve there are long, medium and short fibres that help get the correct shape of the wing profile by building up in layers. You can use this to tie very small monkeys which are more suited to uk waters. It is also stiffer than goat or fox and therefore you don't get tail wrapped as much. Its also perfect fo sunray shadow style flies as well.
