Hiking shirts are effective at blocking out sunlight and cold winds and maintaining and regulating body temperature. They have been loved by hikers for a long time, but at one time they were overtaken by wind jackets due to their lightness and compactness. However, in recent years, with the evolution of nylon materials and the refinement of silhouettes, hiking shirts have been reevaluated. Hiking shirts are unique in that they can be adjusted to suit a wide range of temperatures by adjusting the collar and sleeves. Furthermore, the Nity Gritty Shirt has a variety of pockets, assuming it is worn as a shirt jacket. For hikers who find hiking sacoches bothersome while walking, these pockets will be useful for storing things instead of hiking sacoches.
