Aggregate Worker Pouring Water on his Face

With temperatures hitting 90 degrees-plus, workers in the construction and aggregate industry are looking for ways to stay cool. They might even be tempted to search for gadgets that could give them some relief. Products promising relief from the heat abound, ranging from the low-cost sponge to fit inside a hard hat to cooling vests that can cost hundreds of dollars.

We decided to see what’s available for the heat-beleaguered worker. With so many options and so many claims, we also wanted to get readers’ feedback on products they have used and how they performed. We want to know what’s worked for you and what hasn’t, including any experience you may have had with these products we found online. And it might be that after looking at the additional weight and cumbersomeness of some of these items, you decide you’d be better off sweating.
