All-season Merino jersey knit shirt. Regular Fit. Button Front. Chest pocket. Raglan sleeves. Shirt-tail hem. Finely tuned 18.5 micron New Zealand Merino at 195g/m2. Ibex designed this fabric from the need of a weight in-between their Woolies at 150g/m2 and their Zepher at 230g/m2. The weight of the fabric resembles that of a high quality t-shirt. It works well worn next to skin as a baselayer or on it's own. 100% Merino Wool.
