A well known Ultra Runner from Wales helped me out with this choice. It is hard to find anything larger than Large. There is also the rise is outrageous costs. But Harrier…this jacket is absolutely tried and tested. It is also comfortable and at the same time regulates body temperature. I’ve not had to remove this jacket because i’ve gotten too hot. It is a feature that maybe Harrier are unaware of. I could not even feel the sweat beneath, I was evenly balanced in temperature. The delivery was within 24 hours. Outstanding. Top quality Harrier. Trust in a brand has been made. Thank you.
