The Zone Long Sleeve Crewe delivers the warmth and benefits of merino wool needed for active days on the ski slopes, mountain trails, or for demanding days in a chilly city. This women’s base layer has Icebreaker’s BodyfitZONE™ construction, which combines lightweight 200g stretch merino wool with strategically placed merino mesh panels. These stretch panels help regulate body temperature during high-output activities. The Zone Crewe also features flatlock seams that prevent chafing while the drop tail rear hem delivers some extra coverage.
