No chafing, stays in place, stretches with movement
Light enough to layer under the YKYW cycling jacket you viewed earlier
Dries in 15–20 mins

❌ Cons

Too warm for above 20°C; poor airflow in heat
Durability: Good for 1–2 seasons, not heavy pro‑use
Sizing runs small; always check chest measurements
