Ironside makes gear for people who work outdoors in the Great Lakes corridor, and the Thermal Henley is the backbone of their catalog — a three-button placket henley in a mid-weight brushed synth-cotton that holds heat in wet conditions without becoming a sauna when you're moving. The cuffs are slightly extended to tuck under gloves without bunching, and the collar is designed to sit flat under a high-vis vest or stand alone on a mild day. Colors run to dark slate, rust, and a deep pine green that Ironside has been printing since the brand launched in 2171.

This is a shirt for dock workers, construction crews, municipal maintenance techs, and anyone who needs to be outside when the lake wind comes in cold and sharp off the water. It washes hard and holds its shape. The stitching at the shoulder seams is reinforced with a secondary bar-tack, and the fabric has been pre-shrunk to within a centimeter of its life. Nothing fancy. Does what it says.
