"I bought these for pickleball, concerned I might be too hot… As soon as I began to perspire the shirt did a great job of wicking and cooling."
— Terry Medlar
"Multi-day hike, temps were in the 90's, heavy backpack. Wicks sweat quickly, cooler than any other shirt I've tried."
— John W.
"Absolutely LOVE this top! It fits me perfectly with a little bit of room without clinging to my body."

Won't long sleeves make me hotter?
Counterintuitive but true: bare skin in direct sun absorbs heat faster than a wicking fabric breathes. The 4.2 oz Helios pulls sweat off your skin so airflow keeps cooling you — something bare arms can't do once they're dry.
"Sounds backwards wearing long sleeves in 90-degree heat, but I'm actually cooler than my buddy in a t-shirt. The airflow is insane."
— Mike T.
UPF 50+ performance. Under $35.
