To lounge or to lunge? Either way, the Joseph is the jogger for you. It's made with ultrafine merino wool, which has the uncanny ability to warm you up or help cool you down. It also doesn't trap sweat, like synthetic fibers. Moisture is pulled away from your body and escapes through the fabric. The Joseph is also fully fashioned, so it fits your form without all the extra baggage. So stay at home or hit the trail. The Joseph has you covered.
