The technology behind Desoli Zip is based on a simple concept - Let nature do the work. It’s a 100% merino wool base layer that will provide extra warmth all year around. Works perfectly for skiing, hiking, climbing or everyday adventures. The Houdini design department has spent years looking for the right material in 100% merino wool. It’s not easy to find a fabric that deliver to our standards for performance, quality and sustainability. After many meeting of fabric stroking, many prototypes and extensive field testing, we finally landed on the fabric Solid Merino. It’s a super fine 100% merino wool fabric from Australia. Guaranteed mulesing free. We never mix wool and synthetics. The reason is that we now have a completely circular product: Renewable and both biodegradable and recyclable. Solid Merino provides all the benefits of pure merino wool. It’s naturally odor resistant, keeps you warm even when it’s wet and has a cool feeling against the skin when it’s hot outside. The fit is slim and slightly longer for ex.tra comfort. The Desoli Zip will keep you warm on the mountain, in the city and anywhere in between. It works perfectly for skiing, bicycle commuting, climbing or hiking. The Desoli wool series comes in zip, crew, tee, tights and underwear. Find your favorites and mix and match. This product is recyclable and we kindly ask you to return it to us when it’s completely worn out. We have recycle units in all our own stores and at many retailers.
