This is a long-sleeved shirt from the RIDGE MOUNTAIN GEAR basic line. I purchased it in April 2025, thinking it could be worn for hiking or as everyday wear. The tags have been removed, but I've only tried it on at home and haven't worn it outside. It has a basic look that's suitable for wearing in the city, but as you can see in the photos, it's made of a mesh material that allows you to see through it, providing good breathability and making it useful for trekking where you sweat. Color: Gray (Coast Grey) Size: L Retail Price: 17,300 yen Although it is an unused item, it is still a used item, so please understand this before purchasing. Thank you.
