UPF 50+, explained plainly

The women’s golf polo is the one listing on this site with a sun-protection rating. What UPF actually measures, and when it is worth buying for.

What the number means

UPF is SPF’s cousin for fabric: UPF 50+ means the knit lets through less than a fiftieth of the UV hitting it, blocking about 98%. Unlike sunscreen it does not rub off, wash off at the turn, or need reapplying on the back nine.

Why a rating beats a regular shirt

An ordinary light tee can pass a surprising amount of UV, and more when wet or stretched. A rated knit is built and tested for coverage. For two hours of sun a week it hardly matters; for golf, tennis or pickleball season, shoulders and upper back take the dose, and those are exactly the zones a polo covers.

What this polo adds to the rating

Sleeveless cut and wide side slits for a full swing, a stand collar that covers the back of the neck where visors do not, and a high-low hem that stays put when you bend over a putt. Wrinkle-free fabric, so it comes out of a gym bag ready. From $6.99, which for rated sunwear is unusual.

The limits, stated

UPF covers the fabric, nothing else: arms, neck and face still need sunscreen with a sleeveless top. And the rating is about sun, not heat; what keeps you cool is the light stretchy knit and the airflow through the slits, which this shirt has anyway.
