I'm writing this because I saw it in a question post.

I buy ice and put it in this product, then wear it on my back.
I'm very weak to the heat, so I use it as a must-have during tours.
If you add ice at every 40~50km supply point, it's barely bearable.
And one bottle of water and one bottle of ion drink are filled with water
and I pour them all during long uphill climbs.
But on a 40-degree day, it dries up around me.
I want to be strong against the heat ㅠ
