Artilect’s A/SYS-1 Boulder 125 long sleeve baselayer is a men’s crew neck layer made with Nuyarn technology for active use across running, skiing and cycling. It uses 18 micron Australian merino wool wrapped around a polypropylene performance core, combining a natural fibre feel with added strength. Thumb hole cuffs and a dropped back hemline add practical coverage, while a seamless build and raglan shoulders reduce interference through movement.
Nuyarn 125 merino is used in a 125gsm weight, with interlaced eyelet knit zones placed at underarms and other key hot-spots to increase ventilation, stretch and moisture management. Flatlock seams help minimise chafe, and a hang-dry loop supports everyday care between sessions.
Machine washable. Hang dry.
