So my DH (early 60s) likes to go out on his bike a couple of times a week for exercise and mental health. He's got no 'special' biking clothes and just wears long sleeve t shirt and hoody and tracky bottoms. He's a big lad and gets hot sweaty and then cold and damp. I'd like to get him some clothes to wear when he's on his bike but ....not the full on tight lycra set up. What can i get that will keep him warm but not overheat etc. God I sound so lame. I know nothing about cycling attire. budget around £100
