The Desoli Tee is built from Solid Merino, a super fine 100% merino wool fabric sourced from mulesing-free Australian wool and produced in Lithuania. At 17.5 microns, the fabric delivers natural temperature regulation — warmth when wet, breathability in heat — alongside inherent odor resistance, making it a versatile layer for outdoor activity or everyday wear. The regular fit keeps it comfortable across a range of movement, and no synthetic blends are used, ensuring the tee is fully biodegradable and recyclable at end of life.
