Prime Day 2019: Beat the heat with Serena Williams' favorite cooling gear

It's easy to get overworked and succumb to dehydration or heatstroke when you're active under the blazing sun or elsewhere where temperatures can reach dangerous heights.

Serena Williams can relate. The tennis legend is subjected to high temperatures and direct sunlight for hours while she's on the court – but she found the perfect thing to help combat the heat.
