Thank you for viewing. This is CW-X men's innerwear. I used it once, but I'm selling it because I wanted something a bit more tight-fitting. Here's the product description: CW-X Functional Top HIGH PERFORMANCE JYURYU® TOP MESH Crew neck, long sleeves Recommended for sports where upper body movement is important, such as golf, ball games, and marathons. The lines around the shoulder blades support the left and right shoulder blades in a balanced way, expanding the range of motion. It leads to efficient movement using the whole body and reduces fatigue during exercise. Mesh structure releases heat and stuffiness for cool comfort. ・Support areas: shoulder blades, latissimus dorsi, obliques 【Product Features】 ・Main body: Mesh material ・Side panel switching part: Large hole mesh ・Logo: Reflective 【Functionality】 ・Sweat-wicking and quick-drying ・UV cut rate of 90% or more (main body only) ・Stretch ・Antibacterial and deodorizing Features: Compression, quick-drying, deodorizing, UV protection Thank you. #sports #golf #tennis #innerwear #compression #CW-X Sleeve length: Long sleeve Color: Black
