Last year I blew out my knee. I've got the go ahead and I'm going the light route for obvious reasons. I am going to section hike on 2nd week in May and will be starting at Dicks Creek Gap GA up to Winding Stair Gap NC. Do you think the WM Caribou MF will be warm enough? I know WM are very true to temp. I am generally a warm sleeper, except when alot of moisture in the air. I would layer up and use turtle fur cap. I appreciate your time in replying and value your opinion.
