Let nature do its thing - the simple concept behind these boxer shorts made from 100% merino wool. Stay warm with the lightweight and versatile base layer boxer shorts, whether in the mountains, the city, or anywhere in between. Ideal for hiking, biking, skiing, and climbing. The design department at Houdini has spent years finding the right material. It wasn't easy to meet our standards for functionality, comfort, and sustainability. However, we succeeded and chose Solid Merino. A fantastic material made from 100% Australian merino wool. Absolutely mulesing-free. The Desoli boxer shorts keep you warm when it's icy and also have a cooling effect in warm temperatures. Merino wool retains its warming properties even when wet and is naturally odor-resistant.
