This is a Montbell Gore-Tex hat. Size: S Color: Dark Fuchsia (Pink) The condition is excellent with no noticeable damage. The following is quoted from the web page: ■ All-weather hat This all-weather hat uses fabric with a calm, cotton-like texture. Seam tape is applied to all seams, including the connection between the main body and the brim, ensuring high waterproofness. The mesh lining provides a comfortable fit even when you sweat. ■ UV CUT material It blocks up to 98% of ultraviolet rays (test results with black fabric), so you can use it with confidence for outdoor activities. * The UV protection rate is the measurement of the fabric itself. The UV protection effect may be lower depending on the shape of the product, such as mesh hats. * With sun visors, the effect of blocking UV rays is partial due to the structure. ■ Material Features <Gore-Tex Fabrics 2-layer> The Gore-Tex membrane is an extremely thin, light, and strong film with countless microscopic pores. The size of these pores is much smaller than water droplets, so water, snow, cold wind, and cold air cannot enter from the outside. On the other hand, these microscopic pores are large enough for water vapor to pass through, effectively releasing sweat vapor to the outside and creating a comfortable environment for the skin. 2-layer is made by bonding the Gore-Tex membrane to only the outer fabric, and it is always used with a lining to protect the membrane.
