What is the male version of wearing your boyfriend’s hoodie?

Hi! My boyfriend has been going through a lot lately and I wanted to give him something of mine to comfort him. He’s given me stuffed animals and t-shirts and hoodies over the years that all make me feel better when I’m down. What can I give him that would provided comfort and remind him of me? He’s a tough guy so I know stuffies or my clothes would not be something he’d like. Should I maybe write a love note? Open to all ideas!
