The long sleeve 1/4 Zip Turtleneck 200 from Woolpower is great for keeping the body’s core temperature regulated in cool to cold climates. This Merino wool base layer shirt with a quarter zip turtleneck for ventilation is made from Woolpower’s superior Ullfrotté Original 200 g/m² terry loop design featuring no lengthwise seams, minimizing chaffing and rubbing during peak physical activity. Ullfrotté Original wool fabric with smooth, soft terry loops facing the inside and flat synthetic fibers lining the outside allows this wool base layer shirt to optimally maximize body heat retention by trapping the body’s natural heat as well as maximizing moisture wicking away from the skin. Responsibly made in Sweden.
