Simple black T-shirt with white lines on the sides. - Size: S (JP: M) - Color: Black - Design: Simple design - Features: White lines on the sides This is a thin merino wool T-shirt. It can be used year-round, as a base layer in summer and an underlayer in winter. I have a constitution that gets itchy with merino wool, so I wore it a few times after buying it and it's been sitting in my drawer. There are currently no holes or moth-eaten areas. Recommended for those who want to reduce luggage not only for mountain climbing but also for long trips!
