Artilect’s Women’s A/SYS-1 Boulder 125 long sleeve base layer uses Nuyarn technology with 18 micron Australian merino wool wrapped around a polypropylene core. The 125gsm construction combines a lightweight feel with a thermo-regulating structure for active use across running, skiing and cycling. Thumb hole cuffs and a dropped back hem add practical coverage, while the crew neck and modern easy fit keep the silhouette clean for layering or wearing on its own.
Vented eyelet zones sit at key heat and moisture areas, including under the arms, to support ventilation and moisture management. A seamless design with raglan sleeve shoulders and no-chafe flatlock seams helps reduce interference through movement. The fabric is Bluesign approved, with non-mulesed wool and ethical production and wool sourcing stated.
