Winter: This past winter, on days down to about [cold]
Summer: I wear the goofy-looking Sunday Afternoonsprotection on the water. Skin cancer is a concern, but so is eye damage from reflections off snow and water.
Different seasons do require different fabrics perhaps. Just about to start a backpack and my button down light hiking shirt is drenched with sweat. It’s already pre-broiling hot out west… Soooo I picked up a Patagonia Cool Capilene Sun hoodie as the fabric is light and cools to the touch. I’ll need a cool mesh cap to go with it and, as a backup, using jazzmom idea of a bandanna pinned to said ball cap. |

That pinned bandana gives several benefits: shade, and if wet,cooling. That it could also be drying out from a rinsing is an added bonus.

I have tried a couple of sun hoodies and find them quite a bit warmer than the button up shirts. My bamboo hoodie from the Grand Canyon is really nice when wet, but once dry is very warm. Best thing I learned from the river guides: on a really hot day, take a spare shirt, soaking wet, in a zip-lock bag. Halfway through the hike, swap shirts.

So, what do you all think about hat color? Do you think dark colored sun hats will make a difference heat-wise? I was just at REI (my 23 year-old son's feet are apparently *still* growing... the member coupon came in handy!) and picked up a black sunhat from the clearance bin. Will it be hotter than my pale blue one? (Same quick-dry very lightweight fabric.) I have tried a couple of sun hoodies and find them quite a bit warmer than the button up shirts. Me too, and the synthetic ones get stinky in a day. Mine have just become everyday wear, or for paddling. |

In my 47 years of experience in the desert southwest the darker the fabric the more heat it absorbs. Black is a serious heat sink, good for cold winter but not good for the hot season. If the fabric has no insulation underneath like a Tilley then it will transmit the heat right through to your noggin. If it has some insulation or you can find a way to add some that will mitigate the issue somewhat.

Tilley hat for me, as evidenced in my avatar. I broke down a couple years ago & bought a Tilley. Good investment. Fits well, durable. Finally found a good full brim I'm happy with. |

Some reading: www.nature.com/articles/283373a0: "The amount of heat gained by a Bedouin exposed to the hot desert is the same whether he wears a black or a white robe. The additional heat absorbed by the black robe was lost before it reached the skin."

May very well be incorrect on this, but as far as robes go, black would probably be preferable in a desert climate, as the black would absorb the heat during the day and keep you warmer during the night, but not make you hotter during the day. As far as hats go, all of that extra heat would be absorbed by the human body. There's not enough hat to absorb it on its own. |

Cloth does not absorb heat, so it is of no use in storage for the night. Any breeze would dissipate the heat absorbed by a black robe, but less breeze can get under a hat. link |

Well, I guess we know why they were in the clearance bin! :D
I wore it outside this afternoon and there's not a noticeable difference at 55-60 degF. It's so lightweight and breathable, almost mesh; I'm guessing there's not much difference between it and my hair, which is almost as dark.

This is a question for science. I had read ages ago that the black Bedouin robes were cooler because they set up a convective flow of air due to the heating on the outside. But also remember that what we are talking about is radiative heating which is essentially light. Light that human eyes do not see. It may look black in our visual range but could possibly be bright reflective white in the thermal range. A good sunscreen does this for your skin in the UV range. Also the R value of the hat between the outside and your head would have an impact as said before. |

Tilley for hiking, driver cap for daily use. Sometimes take one of those just for the fun of it. Gets a quizzical look on the trail.
EVent baseball cap for incessant rain, but recently bought a Montane rain jacket that has the best hood/brim combination I've ever seen. might not need a brimmed hat at all for wind driven rain.
Hats are always on my head though. Got treated for a basal cell carcenoma a couple years ago.
