Artilect Men's Boulder 125 Long Sleeve ½ Zip Baselayer {ART-2211121}

Artilect’s A/SYS-1 Boulder 125 Long Sleeve ½ Zip Baselayer uses Nuyarn technology to combine merino wool with a performance core for active wear across running, skiing and cycling. It is built around 18 micron non-mulesed Australian merino wool, wrapped around a polypropylene core for added strength, with a thermally regulating structure intended for next-to-skin comfort.

Ultra-light 125gsm Nuyarn merino construction is paired with vented eyelet zones at key hot spots, including under the arms, to support breathability and moisture management. A deep set half zip allows on-demand ventilation, while the dropped back hemline adds coverage. Seamless construction and raglan sleeve shoulders are matched with no-chafe flatlock seams for reduced interference through movement.
