Call Lou from
www.foxwear.net. All his clothing is custom made... yet the prices are great! I am sure he can make a coat or any of his other cloting in just about any size you'd need.
I have the EVap coat and use it from 50F down to 2F. I also have his riding tights for Winter use and they are phenominal. So far I've been down to 15F without the slightest bit of being cold. Also the material is extreamly wind proof so that helps a lot, yet allows sweat to leave easily. There may not be some fancy lable on the clothing Lou makes, but all his stuff is very functional and well made.
Happy riding,
André
