The Desoli Thermal Half Zip is a heavyweight merino wool base layer built for cold-weather activities, from ski touring to alpine expeditions. Constructed from Solid Gridmerino™ fabric using 100% pure 17.6 μm merino wool at 270 g/m², the grid weave delivers substantial insulation while allowing airflow to manage heat during high-output efforts. The high collar and half-zip closure make it easy to layer and regulate temperature on the move. Slim fit and made from fully biodegradable, recyclable fibers, it performs as a standalone mid-layer or as part of a winter layering system.
