This is a Montbell Wickron ZEO T-shirt, men's size S, product number 1104936, retail price around 4000 yen. Because it's Wickron ZEO, I used it for hiking and cycling, except in mid-winter. I'm selling it to organize my clothes for the change of seasons. I washed it in a laundry net and handled it with care to avoid damage. Due to the nature of Wickron ZEO, there is some pilling, snags, and stains. Please consider purchasing only if you prioritize functionality and don't mind these minor imperfections.
