Lite and dry!
Was on the AT in Shenandoah. The day was miserably rainy and windy. Hat was perfect on my bald head. Breathed! Kept my hood off my face and rain out of my face--my glasses barely got wet! Wicking was excellent which allowed the cap to dry very fast! I once only wore this hat to run, but it will go with me to the mountains from now on for such eventualities. I will need to remember that I take because it weighs nothing!
