Irvin are bulky but that's part of the attraction for me as it makes them incredible warm to wear with a lovely feeling of insulation from the outside world. I remember an essential 200 mile motorbike ride around this time of the year as we were moving home. Although very cold it was dry. The rear of my full face helmet interfaced perfectly with the collar of the jacket to allow a warm and surprisingly quiet ride.
My Irvin jacket was bought new over 35 years ago and it still looks like it.
