🏆 Our Verdict
For extended outdoor activity (fishing, hiking, running), a UPF 50+ sun shirt is superior — it provides consistent, full-spectrum protection without reapplication. Use sunscreen for exposed areas like your face, neck, and hands. The best protection combines both: UPF clothing + SPF 30+ sunscreen on exposed skin.
