FWV Neck Air Conditioner with Cooling Plate, 5500mAh 3-24H Working, 5-Speed Quiet 30dB, LED Display Personal AC, USB-C Bladless Wearable Cooling Neck Fans that Blow Cold Air for Men Women Kids Blue

Maybe try a neck fan with a cooling plate. I don't understand the science, but cooling plates work SO well! This is just a random one I found on Amazon. Make sure you get one that allows the cooling plate to work when the fan is off.
