The Desoli Shirt is crafted from Solid Flannel Merino™, a woven fabric made entirely from 17.5 μm pure merino wool at 193 g/m², placing it firmly in the mid-weight category suited to fall, winter, spring, and cool summer evenings. Its relaxed, minimalist cut includes a buttoned chest pocket, classic buttoned cuffs, and a side split for ease of movement, making it equally at home on the trail or in town. The unblended wool construction means the garment is fully circular — recyclable or compostable at end of life — while the superfine fibers offer next-to-skin comfort soft enough to wear as a base layer within a technical layering system.
