Nature meets technology in a minimalistic mid-layer in 100% merino wool. Warm, breathable and highly versatile. Use it all year around for skiing, climbing, hiking or any other adventure.Wooler Halfzip is made in a 100% merino wool fabric called Wooler Gridmerino. The grid construction builds a comfortable layer of air for insulation and allows air to flow through the garment. Wool is also naturally odor resistant. Wooler Gridmerino is produced by Reda in Northern Italy. It’s the ultimate combination of natural material and technical execution. The design team at Houdini almost couldn’t believe it was pure wool because of its precision and technical qualities. Besides the performance qualities, Wooler Gridmerino takes big steps from a sustainability perspective. The material is made from renewable fibers and is biodegradable, making it completely circular. The wool is also ZQ-certified, which controls animal welfare as well as social and environmental sustainability. Reda owns the entire production chain, from the wool farm in New Zealand to the finished fabric in Italy. This is very unusual and gives an unmatched control over production methods. Wooler Halfzip is designed to work for any activity all year around. It will keep you warm and cozy and is a great natural alternative to a synthetic fleece.When your Wooler Houdi is completely worn out we kindly ask you to return it to Houdini for recycling. We have recycling units in all our own stores and at many retailers.
