Built for high-intensity pursuits on bikes, skis, and alpine trails, the men’s Zone Long Sleeve Crewe delivers all the benefits of merino wool with some tactical ventilation. It features Icebreaker’s BodyfitZONE™ construction, which combines lighter 200gm stretch merino wool with strategically placed merino mesh panels to improve temperature regulation during activities. Icebreaker’s corespun fabrics further enhance this base layer’s durability. The gusseted side panels prevent the shirt from rolling up, and flatlock seams help prevent chafing. The tops' crew neck design gives it stylish appearance when worn on its own.
