The VENTILATE ACTIBREEZE™ SINGLET was engineered by the ASICS expert team for running in warmer conditions. The ACTIBREEZE™ technology is an advanced breathability technology developed to keep runners cool and comfortable. This top's strategic body-mapped fabric provides advanced ventilation in key heat zones. Lightweight and quick-drying, it's also made with large slits on the sides that are functional for improving airflow and increasing freedom of movement. At least 50% of the primary material for this garment is made with recycled materials. ASICS - Ventilate Actibreeze SingletMen cilantro
