📊 Pros & Cons
✅ Pros

- No fabric flutter, stays fixed during high‑speed efforts
- Stretches fully with pedalling motion, no restriction
- Smooth next‑to‑skin feel, zero chafing
- Thin enough to layer under any jersey; works alone in warm weather
❌ Cons
- Only for cycling/sport — too tight, not for casual wear
- Not insulated; not for temperatures below 10°C
- Compression fit feels firm initially
- Sizing runs small — measure chest carefully
