Neck Cooling Tube, Reusable Wearable Cooling Neck Wraps for Summer Heat, Cooling Starts at 28°C, Relief for Hot Flashes and Fever Smart ice Neckband for All Sports Outdoor Activities (S)

Well, 2 major issues: first, this doesn't stay cool long enough to have any measurable impact, and it's so rigid that it makes my neck hurt to wear.

I recently ordered this product to wear at an outdoor concert. Unfortunately, it was room temperature before I even arrived at the event. I'm sure it worked for a little bit, but unfortunately, in the time it took me to travel to the venue, it had already exceeded its useful limit.

This neck cooler is a must-have companion for the hot summer. It reduces body heat by cooling the neck and prevents heatstroke. I can put it in direct contact with my skin and enjoy the cooling sensation.
