Men's eco-responsible t-shirt inspired by the mountains, with an original design of the Ubaye valley and the Chambeyron peaks. 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°.

I've been a fan of the Ubaye for a long time, and I was looking forward to a t-shirt on this theme! Nice graphics for the Brec, nice colour combination, top quality fabric. I'm going to order the Clarée one, which also deserved to be in the collection 😉
