Sunblock is all fine and good, but the more gentlemanly alternative to smearing your face with an ounce of grease is some summery headgear.
The right hat can make you look even more dapper in the heat, and while your fellow men sweat it out unattractively you can look like a British secret agent in the Bahamas.
Here's nine of the best:
One of London's most revered hatters crafts the ultimate travel hat, which rolls into a tube during transit.
The bucket may be the most casual lid on the list but this patchwork seersucker version from Brooks has plenty of sprezzatura.
Natural straw hats give you a bit more diversity than blinding white panamas, but all of the panache.
The classic ivy cap rendered in a cool linen and cotton blend is simply a style necessity.
This hybrid between a panama and a boater made in the U.S.A. definitely has a dandified edge but is more versatile than a classic boater (see below).
Loro Piana may be best known for cashmere but they have an eye for straw as well as this deep blue panama can attest.
This natty, South of France-worthy alternative to straw is made of a calico-cotton blend and packs a serious retro punch.
As you can tell we're on a blue straw kick this season, and this classic Panama shape's striped band really sets it off.
So dandified and old-timey at this point, the boater can really only be worn with seersucker or white linen suits, but that's hardly a bad thing.
