Bought the top thinking it would be a weird fad item to own, didn’t intend on wearing it. I had it in my bag during a 12 hour loop race and temps were unusually high. After about 2 hours I was suffering so I threw this on and the cooling effect was amazing, I completed the race instead of likely dropping. It actually looks cool when you’re running and it’s 100% functional. I bought the long sleeve version as well, it’s that good.
