Carol B, just saw this voluntary recall of sun wear products on the Patagonia website - might help explain the lack of stock:
"We recently discovered that some products in two of our sun protection lines—Capilene? Cool Daily and Tropic Comfort—do not meet the 50+ UPF (Ultraviolet Protection Factor) rating we claimed for them. If you own one of these products, please know: They still offer solid UV protection. It’s just not as much as advertised.
?
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% 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."
