The Desoli Light Crew is a slim-fit base layer built from 100% pure 17.5 µm merino wool in a lightweight 150 g/m² knit, offering natural temperature regulation, odour resistance, and moisture management across all seasons. A slight back drop and seams positioned away from high-friction areas keep the fit comfortable under a shell or on its own, while extended sleeves with hidden thumb loops add coverage during high-output activities. Because the fabric uses no synthetic blends or chemical treatments, the garment is fully biodegradable and recyclable at end of life. It suits everything from summer trail runs and cycling to winter ski touring and ice climbing.
