I sweat a lot when I exercise. After an hour of running at medium intensity (~150bpm avg HR) in 20°C @ 50% humidity, I am literally drenched in sweat. I can wring my clothes and sweat will pour from it. It’s difficult to find clothes that are comfortable to wear for my long trips.
Sweat wicking clothes and a bandana on my head. The bandana will be soaked when I’m done with a 5k, but it keeps so much sweat off my body and out of my eyes.
