Nice hat for the New Mexico trip
In case you want a nice cool hat to protect your head and neck, I found one at Amazon and they work well. The top is ventilated so it is cool but it protects your ears, face and neck from this hot 100 degree sun. It has a strap to keep it from blowing off. A large is 24.99 + 5.99 shipping. There are many more listed below.
Cool long sleeve T-Shirts
Just in case you feel like your arms are burning up in this heat on the runs, I found some long sleeve cool T-Shirts with UPF 50 protection. We ordered a couple since we will probably be top down a lot on the Head for the Mountains trip.
We got the shirts. The shirts are very nice and kind of silky feeling. They really should keep us cool and block the sun.
