A pack of cooling towels
The 40"x12" towels are machine washable. And for a wearable option, the brand also makes headbands with the same cooling tech!
Promising review: "Summer trip to Europe was HOT this year! I mean HOT! Florence's 104-degree F temperatures made it hard to really enjoy the days of exploring, but thanks to these amazing little towels, I avoided heat exhaustion. So thankful I bought these. I was very skeptical, but I am glad I took a chance because they absolutely made a huge difference. You will still feel hot, and unless you buy this in 'blanket size,' you will still feel the effects of the heat, but they absolutely cool you and bring a respite when it matters. Especially when things are heading to a critical place, they absolutely 100% were a lifesaver for me. Started on my neck, ended up over my head (as you can see in the pic), and I repeatedly placed on my cheeks to cool them as needed." — Cristina Viera
