(Under Armour) UNDER ARMOUR UA HG Compression SL Mock MCM3422 HeatGear Men's M Size I bought this for American football, but I didn't end up using it because I used a pad-equipped type. I hope to deliver it to someone who can make good use of it. Lightweight sleeveless shirt that protects the neck from friction and UV rays while ensuring mobility around the shoulders. Lightweight, supple, and exceptionally comfortable. Keeps the body cool through body temperature control. By changing the position of the shoulder and armpit switching from the conventional model, the "contact feeling" with the skin is reduced. Ideal for sports where friction on the neck from uniforms and shirts is a concern.
