【Perfect Warmth for This Time of Year】 Product Number: JAY230 Brand: CW-X Product Name: Jyuryu High Neck Long Sleeve HOT Type Color: Black Size: M Details: [EVRDRY Fabric] Absorbs and evaporates sweat with threads that have a large surface area and incorporate active microparticles. [XSPEC Technology] Functional material that evolves by pursuing the functions athletes seek (sweat-wicking, quick-drying, UV protection, stretch, antibacterial/odor-resistant, and heat retention). [Jyuryu Pattern] The lines around the shoulder blades support the left and right shoulder blades in a balanced way, expanding the range of motion. In addition, the design with a hole in the center improves the linkage of the movement of the left and right shoulder blades, enabling large arm swings using the shoulder blades. It leads to an efficient running form using the whole body and reduces fatigue. *I wore it a few times under a T-shirt during last winter's marathon. Home cleaned and stored at home. It was very warm and I liked it, but I don't have many opportunities to wear it, so I'm selling it. Material: 90% Polyester, 10% Polyurethane Thank you for viewing.
