They are suitable for a light t-shirt. But I use them more often in winter as a base layer. I usually go somewhere between M and L. I got the Med and it was big enough - too big for what I need. didn't think it was great value for money. I sent them back. I'll stick with the brand I'm used to that I can still find at the best price.
