Soak up the sun in the Eclipse Sun Long-Sleeve T-Shirt

What Our Gearhead® Experts Are Saying:


"I wore this on a hot trail run and barely noticed it was there. It stretched with every stride, and the UPF 50+ meant I could skip reapplying sunscreen on my arms."


Backcountry Romantic Copy

Long sunny days call for coverage that doesn't slow you down, and the Eclipse Sun Long-Sleeve Tee delivers exactly that. Wear it on a midday trail run, a paddle session, or a lazy bike ride around town, and let the stretchy knit move with every reach and stride while UPF 50+ handles the sun so you don't have to think about it.

Frequently Asked Questions

  • How should I choose a size in the women’s Outdoor Research Eclipse Sun Long-Sleeve T-Shirt?
    The Eclipse has a relaxed fit with stretch, so it offers more room than a close-fitting performance top. Use the product page size chart and prioritize bust and arm length for a comfortable fit with full sleeve coverage.
  • What conditions suit the Outdoor Research Eclipse Sun Long-Sleeve T-Shirt best?
    Its lightweight, breathable, quick-drying fabric and UPF 50+ protection make it a strong choice for warm, sunny hikes, runs, and climbing days. It manages sweat and incidental splashes, but it isn’t a rain layer or an insulating top.
  • How does the Eclipse Sun compare with a fitted running shirt or a weather shell?
    The Eclipse’s relaxed cut and full sleeves favor comfortable sun coverage and layering, while a close-fitting running top may feel less loose during fast efforts. Unlike a shell, it provides no rain protection, so bring an appropriate outer layer when weather turns.
  • How should I layer the Outdoor Research Eclipse Sun Long-Sleeve T-Shirt for hiking or climbing?
    Wear it next to skin beneath a pack, climbing harness, or running vest; its stretch and split side hem support movement. In cool or wet conditions, add insulation or a shell over it rather than relying on the shirt for warmth or weather protection.
  • How should I care for the Outdoor Research Eclipse Sun Long-Sleeve T-Shirt?
    Follow the sewn-in care label; for synthetic performance fabric, cool washing, avoiding fabric softener and high heat, and air-drying when practical help maintain its feel and function. Store it clean and completely dry.
