I wear the Pfanners here in Florida as do everyone that I work with. Summer and Winter. Anytime we are using saws, which is most days. !00 degrees and 95% humidity is hot even in a Speedo. I would never use a chainsaw while wearing my Speedo. I feel it's important to operate as a professional. It makes sense to offer myself and my co-workers as much protection as I can. We hydrate ourselves well as part of the plan and we do just fine in the "Air that you Wear" here in FLA.
