This versatile, all-mountain fleece is the ideal extra midlayer on chilly or wintery days. Built with smooth-faced, midweight Thermic™ fleece, the Geon is warm, breathable, and easy to layer under insulation or a shell. It’s thick enough to provide a good boost of warmth when the temperature drops and works hard to wick moisture through your layers. Ideal for all kinds of mountain ascents, from hillwalking and hiking to scrambling and climbing.
