Gender: Women's Mammut trekking T-shirt. Purchased at Ishii Sports in Shinjuku before the pandemic, but it was hardly used and has been stored away. Worn twice as a change of clothes after trekking and taking a bath. Not used during mountain climbing. Color is light blue. This T-shirt has a pattern recommended by the store staff. I would like to sell it to someone who needs it while it's still in good condition.
