Depends on how hot and humid it is outside. Even in breathable clothing like Nike Dryfit or any of the thousand knockoffs, in 90+ degrees, high humidity weather, a backpack blocks perspiration evaporating off. It literally becomes a hot spot on your back. He did have one tip I don't entirely agree with to use Vaseline, but instead I use Glide just because I don't care for the consistency of petroleum jelly. Although he mentions long sleeves shirts and a hat with neck guard, he said nothing explicitly about skin or eye protection; people in the sun day after day should be wearing polarizing lenses and high SPF clothing along with sun screen.
Even during monsoon season in AZ, I still find an all-mesh marathon vest like Ultimate Direction Marathon Vest V2 plenty comfortable. I put my phone, flashlight, ID, hand sanitizer, tweezers (for cactus thorns) and keys in it. If I need to I can also put something like a Patagonia Houdini in it for windy / light precip.
Nice! Good tip. Anything to prevent the advance of macular degeneration and cataracts. [1] Maybe that's not settled science - not sure - but it's a cheap preventative. And it's settled enough at least that good sunglasses can be purchased through some FSA/HSAs.
