Proof 72-Hour Merino Polo Shirt
Proof has steadily expanded its 72-Hour Merino collection beyond the original tee, adding everything from the 72-Hour Merino Pant to the lighter Merino Air T-Shirt. The latest addition is the 72-Hour Merino Polo Shirt, bringing the same travel-friendly performance fabric into a slightly more polished silhouette.
The polo is made from ultra-fine Australian merino wool blended with nylon for extra durability. Like the rest of the 72-Hour line, the fabric is designed to regulate temperature, wick moisture, resist odors, and handle repeated wear without demanding constant washing. It also adds UPF 30+ protection, making it a strong option for warm-weather travel, golf, or long days outside.
The cut stays clean and versatile, with a three-button placket, a soft collar designed to hold its shape, and a balanced fit that works tucked or untucked. The result lands somewhere between a performance shirt and a traditional polo, giving it enough structure for a smarter setting without losing the easy feel that defines the rest of Proof’s merino range.
