Spring is the time to pick up sweaters at the thrift. Hard to find this time of year. I have a wool cap that covers my ears that I LOVE. it looks like it is covered with frost when I get into work from how efficiently it moves the sweat. I have a red Merino sweater I picked up for $3 at the thrift. By far my favorite for the 40's with a base layer tech fabric compression shirt. for as light as it is I'm toasty warm and feel reasonably dry.
