Patagonia issued a voluntary recall of products in two of its sun protection lines—Capilene Cool Daily and Tropic Comfort.  The products do not meet the 50+ UPF (ultraviolet protection factor) rating.

Patagonia said in its recall notice, “If you own one of these products, please know they still offer solid UV protection. It’s just not as much as advertised.”

The statement added, “Our tests confirm a range of 17–45 UPF instead of 50+, averaging 34 UPF. The good news is that even at 17 UPF, the products block 92 percent of the sun’s ultraviolet rays. The bad news is that we didn’t deliver on our goal to offer you the highest level of sun protection. We’ve pulled our existing inventory and halted distribution of the affected styles until we can fix the problem.”
