The first thing to know about this hat is that you're meant to get it wet. Dunk it in a sink or the sea, wring it out, wave it for a minute, and the fabric pulls heat off your head as it dries. The listing claims up to 30 degrees of cooling below average body temperature — a number we can't check, though the drop in temperature is real enough on a hot afternoon.
That trick is the fun part; the reason it's our top pick is everything around it. The brim measures three inches and runs level all the way around rather than dipping at the front, so your ears and the back of your neck are covered and not just your face. The fabric is rated UPF 50+ and blocks sun whether it's wet or dry, and the whole hat goes in the washing machine when it starts to smell of sunscreen and sweat.
One size is the catch, and it runs large. On an average head the crown sits low enough that the brim crowds your eyebrows, and you'll want the chin strap snug to keep it where you put it. If you usually take a medium, the Home Prefer will sit better; if hats have always perched on you, this is the one that finally won't.
The brim is soft rather than wired, which is why the hat folds into a bag, but a crosswind can peel it up. The cooling also fades as the fabric dries, so a long day means finding water again — easy on a boat, a bottle on a trail. Neither has stopped us reaching for it on days we knew were going to be hot and wet.
Pros
- Cools for a stretch once soaked

- Machine washable with a chin strap
- Folds flat into a bag
Cons
- One size runs large on average heads

For hot, wet, active days this is the one we hand people: UPF 50+ fabric, a three-inch brim all the way around, and cooling that switches on when you soak it.
