Out for a short 10-mile walk in temperatures somewhat higher than 100F/38C. Not 40C, so it's not really hot yet 😉.
I did my first walk with a harness umbrella holder and WOW did it make a difference! I've got a hiking umbrella (reflective silver on top and black on the bottom), but it's a bother to always carry it. The holder just takes care of that. Walking in permanent shade really helps.
