This long-sleeved T-shirt is from Ternua, a brand of Ishii Sports (ICI). The lining has a waffle texture (see photo 9), and the sleeves are designed with slits. You can put your thumbs through them to cover the back of your hands. I've only used it 2-3 times and stored it at home, so there are no noticeable scratches or fraying, and I think it's in good condition. Recommended for mountain climbing, hiking, and trekking.
