DF Mesh Merino Long Sleeve Worn twice. Stored at home in the closet since then. Dark blue long-sleeved cut-and-sew made of wool blend, raglan sleeve design. - Material: 98% wool, 2% nylon - Size: UNISEX L - Color: Slate Blue Long sleeve that overcomes the weaknesses of wool DF Mesh Merino is a base layer series made with original fabric from Yamato Michi, which eliminates the drawbacks of conventional 100% merino wool, such as "difficulty in drying," "stickiness when wet," and "heat buildup," at a high level. While maintaining the comfort, deodorizing properties, and moisture-regulating properties unique to wool, the two-layer (Double Face = DF) mesh structure absorbs sweat and dries quickly, prevents heat buildup, and when layered with a shell, stores air in the fabric to keep you warm. A slim-fit pattern that doesn't let sweat escape from the skin, this mesh long sleeve is perfect for high-intensity activities such as trail running and fastpacking. Thank you for viewing.
