This undershirt for men is specially conceived for combination with business shirts. The highly elastic, innovative shape zone with its netlike raster shape at the midriff has a shaping effect. Inserts under the arms and at the neck assure good thermal regulation, breath-ability and very good moisture absorption. A special thread has an odourinhibiting effect. Due to its hydrophilic properties on the inside, the shirt absorbs perspiration. The hydrophobic exterior prevents formation of sweat marks on the business shirt. A deep V-neck allows the top buttons of the shirt to be opened. The extended back section prevents it from slipping out of the trousers.
