Most caps sold in this country were drawn up somewhere cooler. Closed cotton weaves, a sweatband that holds water, and a crown that gives up by ten in the morning. This one was specified the other way round, for humidity coming off the Gulf and sun that sits directly overhead. Olive kills glare and hides dust, which is why it tends to end up in the car rather than the wardrobe.

HYDRO ARMOUR

A tightly woven performance fabric finished with a durable water repellent, so sweat and rain bead on the surface instead of soaking through.

UPF 50+

Rated to block more than 98 percent of ultraviolet light, across a full round of golf or a long afternoon outdoors.

Laser-cut venting

Vents cut through the panels rather than stitched in, so air crosses the crown instead of sitting against it.

Vintage Fit

A relaxed six-panel crown at low profile, unstructured so it settles closer to the head and softens with wear.
