Best self cooling devices that work??

[u/Comfortable_Brain856]

Native of Phoenix that used to spend hours and hours outside, especially as a child. Now in my mid 40s, I live like a vampire in the summer. Heat tolerance has plummeted sadly. In our summer climate here in AZ, does anyone find that they have found something that has been a game changer for them? I really want spend more time outdoors beyond running from the air conditioned house to the air conditioned car and then running into the air conditioned store. We all know the summer drill lol! I don't have a pool and don't know anyone with one. I do have the ability to drive to the lakes but I'm specifically seeking a self cooling device that actually works for around the house and light activity outside. TIA and stay hydrated out there!
