I have one of these…

This is a NZ product but they do post overseas. It’s bloody handy to put on when warming up, just switch to your coat before you go in, then put it on again after. I soak mine, then put it in the fridge at home or in the truck for an hour, lovely and cool…
Big bonus is that it doesn’t make me or my white shirt wet… the see-through look is never a good one :lol:
I also have their horse boots as well to cool down legs after working on hard ground, or the XC, they are also FAB!
