I'm in the Northeast so we have thick briar-y low growth in the best deer spots. I wear the First Lite Sawbucks. I originally got them for upland hunting but I have worn them just about every day from Sept to Dec. I wear them with no base layers in to about 50 degrees, FL Fuse around 40, and a pair of polyester joggers under around 30 degrees. They aren't totally silent like microfleece or wool, but they're quiet enough to bow hunt in.
