What Is TempoCool Fabric?

How to Wear It
Wear it solo for sun-exposed road runs, trails, and outdoor workouts; the long sleeves protect arms without overheating thanks to quick-dry breathability.

Sun protection without the sweat
I run in Arizona and this shirt is a lifesaver. The UPF 50+ protection means I don't have to slather sunscreen all over my arms, and yet it's somehow cooler than wearing a short sleeve. The fabric dries so fast that sweat never lingers. It's become my default for every sunny run.

Great coverage, nice fit
Love the long sleeves for sun protection and the v-neck doesn't feel suffocating. The recycled polyester feels good quality. Runs slightly small, so consider sizing up.

Dermatologist-recommended habits made easy
After a skin cancer scare, my dermatologist insisted I cover up outdoors, and running in the sun was my biggest risk. This tee solves it beautifully — full arm coverage with UPF 50+, yet it stays cool even on 85-degree mornings. The v-neck is flattering without exposing too much, and it never feels sticky or heavy. I've washed it weekly for two months and the fabric still looks and performs like new.

Nice shirt, snug fit
The sun protection and quick-dry performance are legit. But this fits very snug through the shoulders, so I'd recommend sizing up if you have broader shoulders or like a looser feel. Quality itself is good.

Cool on hot days
Genuinely feels cooler than bare skin in direct sun, which sounds like marketing nonsense but is real. Dries fast, no odor buildup. The sleeves are a touch long on me but I just push them up.

Beach and trail approved
I use this for running AND as a beach coverup and it's great for both. Zero sunburn through the fabric after a full day outside. Soft, light, and the v-neck style is cute enough to wear casually.

Solid value
For $14 this is honestly hard to beat. UPF protection works, it's lightweight, and it washes well. Not the softest fabric ever but perfectly comfortable.

Best hot-weather running top I own
I've tried all the big brands and this budget shirt outperforms several that cost twice as much. The breathability is outstanding and the fabric has a slightly cooling feel against the skin that I really notice on humid mornings. It doesn't cling when damp, which is my pet peeve with most running tops. Already ordered a second color.

Shrunk in the wash
Loved this shirt for the first few weeks — great sun protection and cooling. But even following the care instructions, it shrank noticeably after a warm wash cycle and the sleeves are now too short. Maybe stick to cold wash and hang dry only.
