Highly recommended as a summer hiking hat (including midsummer)! It is about 5mm longer and wider than Crushing It Cap or VaporLite Cap, which are sunday, afternoon and summer caps with different brim widths and lengths, but the brim is much longer and wider when viewed or worn in reality. The brim is also made of soft material like the Crushin It Cap or Vaporlite Cap mentioned earlier, so it is very comfortable to wear! Summer (including midsummer) mountaineering hats include Crushin It Cap (mesh material on both sides of the hat), Vaporite Cap (a material that is breathable and absorbs sweat well on both sides of the hat), and the Ultra Trail Cap (mesh material in the upper left and right parts of the hat). Whether you choose a hat, moisture absorption, quick-drying, breathability, and lightness are all the best! (All three types of hats are one-size-fits-all)
