Men's eco-responsible mountain-inspired T-shirt with the Masherbrum slogan "Because we love mountains". This t-shirt is pleasant to wear all year long and will accompany you in your light activities as well as in your everyday life, thanks to its soft 160g/m² blue jersey, made of 50% GOTS certified organic cotton and 50% TENCEL Modal (fiber from beech wood). This unique textile makes it a very soft, comfortable and resistant T-shirt for everyday use. This Masherbrum product is knitted, dyed and made entirely in the European Union, and printed and packaged in Grenoble (38).

This item is quite close to the body. If in doubt, choose the next size up. We recommend machine washing on the reverse side and at less than 40°.

This is not the first shirt I've bought from Masherbrum, always so comfortable, I've never had this comfort with other shirts. Incomparable.
