BAMBOO SHOOTS SHORT SLEAVE OPEN COLLAR SHIRT color / GRAY size / M MATERIAL / 100% Nylon This item is from the 2024 Spring/Summer season and was purchased from the official website. I am selling it because I haven't had the opportunity to wear short-sleeved shirts. I wore it once in the mountains and once in the city. From the official website: This shirt follows the details of military chambray shirts. Ventilation is subtly placed on the sleeves.
