Highly recommended as a hat for summer hiking (including midsummer)! The brim is about 5mm longer and wider than the Crushing It Cap or VaporLite Cap, which are sunday afternoon summer caps with different widths and lengths. The brim is also made of soft material like the Crushin' It cap and the Vaporite cap mentioned earlier, so it's really comfortable to wear! Summer (including midsummer) mountaineering hats such as Crushin It Cap (mesh material on the left and right sides of the hat), Vaporite Cap (material that is breathable and sweat-absorbent on the left and right sides of the hat), and this product, Ultra Trail Cap (mesh material on the left and right parts of the upper part of the hat), which No matter which hat you choose, moisture absorption, quick-drying, breathability, and lightweight are all the best! (All three types of hats are one-size-fits-all)
