If you're looking for sun protection arm sleeves, the most important feature is a UPF (Ultraviolet Protection Factor) rating, not just the material or color.

Here are the key things to look for:

  • UPF 50+ – Blocks at least 98% of harmful UV rays and is the best choice for prolonged outdoor use.
  • Breathable, moisture-wicking fabric – Keeps your arms cooler by moving sweat away from your skin.
  • Lightweight stretch material – Comfortable for driving, cycling, running, hiking, gardening, or outdoor work.
  • Anti-slip bands – Help prevent the sleeves from sliding down during activity.
