I recently purchased an Arlen Ness kangaroo skin 1 piece suit, the same suit that Troy Bayliss uses.
The suit has very good quality CE approved armour in all the high impact areas.
What amazed me the most was how light the suit is - it is almost half the weight of cow leather and twice as strong. Placement of the stretch panels around the shoulder and ribs is brilliant allowing me more flexibility than any other suit I have used.
A removable liner that can be washed is a great touch and helps keep the suit smelling fresh.
This suit is very comfortable a can be worn all day without discomfort in the usual areas.
I would highly recomend this suit to anyone looking for a top of the range suit at a reasonable price.
