The Desoli Thermal Half Zip is a heavyweight merino wool base layer built for cold-weather pursuits, from ski touring to alpine expeditions. Constructed from Solid Gridmerino™ fabric using super-fine 17.6 µm pure merino wool at 270 g/m², it delivers substantial insulation while a grid structure maintains airflow during high-output activity. The high collar and half-zip design make it easy to layer and regulate temperature, while the slim fit sits cleanly under outerwear. Pure, unblended merino wool means the fabric is naturally odor-resistant, stays warm when wet, and is fully recyclable or compostable at end of life.
