Primary Material Leather
This garment is fitted with impact protectors for the elbows and shoulders. A pocket is provided for an aftermarket back protector.
There are vents in the chest and perforated leather in the shoulders to allow airflow movement through the garment. The thermal comfort rating is based on tests of the breathability of the garment when all vents are closed. The thermal comfort of this product may be better when the vents can be opened.
