The ASICS METARUN Short Sleeve Top is a lightweight running shirt designed for warm training sessions and runners who value targeted ventilation. ASICS uses ACTIBREEZE technology with body-mapped fabric zones to improve airflow around key heat areas. The knitted material is intended to feel light, breathable and comfortable, while the shoulder-seam placement supports freer arm movement through the stride.
This model is best viewed as a technical short-sleeve layer rather than a casual cotton tee. Its ventilation-focused construction can suit road, track and treadmill running, especially in warmer conditions. Fit and comfort remain personal, so check the current ASICS size chart and allow room for normal upper-body movement before ordering.
The catalogue entry covers the METARUN Short Sleeve Top family; men's, women's, colour and size options are variants rather than separate products. Specifications and the US$85 regular reference price were checked against ASICS' official US product page on 23 October 2026. Availability and selling prices can change.
