George, I'm not wool tolerant (Per my Dr. nobody is allergic to wool.) so I can't help with those suggestions. I have a PI heavy rain jacket with vents and a long flap I can lower to cover my backside that works very well. There's no model name on the jacket, BTW. Heat loss is greatest at the head, so a cover is important. Dry and warm feet are my second priority followed by mittens for the hands. I have a Foot Joy long sleeved T-shirt that my son gave me that works as well as he said it would. It holds body heat with the vents closed, but once the vents are opened or the jacket removed it doesn't ventilate too quickly to cause a chill.
