finetrack Merino Spin Thermo Zip Neck Color: Dark Gray Size: M Length: 67cm Width: 45cm Sleeve Length: 54cm Used, worn 2-3 times. This item is from finetrack, a Japanese brand that releases high-performance outdoor wear. Their underwear is particularly well-regarded. I believe this item is the Merino Spin Thermo Zip Neck from about 10 years ago. At that time, the wool content was less than it is now, with 86% polyester and 14% wool. A hybrid base layer of merino wool and polyester. It combines the heat retention and moisture control properties of merino wool with the sweat-wicking and quick-drying properties of high-performance polyester, making it less prone to stuffiness and quickly drying sweat. There is a small amount of pilling on the left elbow (last image), but the item has been worn few times, so the condition is good. Please note that this is a fall/winter item.
