The Mizuno Long Sleeve Compression Top is a base layer built to keep athletes warm, dry, and moving freely. Mizuno DryLite® Technology uses a dual-filament yarn to pull excess moisture away from the body, while a true compression fit supports muscles and helps regulate temperature during warm-ups, games, and cold-weather practices. Worn close to the skin, it manages sweat in the heat and traps warmth in the cold, making it a true year-round layer, and the streamlined fit reduces chafing under chest protectors, jerseys, and pads.
