If you put function above all, wear a hoodie and a white and navy crew-neck t-shirt. Get a little creative in the footwear department and dial down this ensemble by finishing off with a pair of grey athletic shoes. So as you can see here, it's a sharp, not to mention spring-friendly, outfit to have in your seasonal arsenal. This pairing demonstrates that as a man in his forties, you have a wide array of sartorial options.
