Care Guide:
Machine wash with like colors in warm water with a mild eco-friendly soap, then hang to dry. On the road or in the wild? Wash with shampoo or mild soap in the shower, rinse thoroughly, squeeze out excess moisture, and hang to dry. Merino dries super quickly!
IMPORTANT: Always wash black garments separately to avoid color transfer. Never bleach or use fabric softener. Bleach destroys Merino, while fabric softeners coat the fibers, minimizing their ability to manage moisture and regulate body temperature. Garments damaged due to improper care cannot be refunded or exchanged.
Material:
Our Merino wool is sourced from a sheep farm in Australia. Our yarn is engineered and spun by Sudwolle Group in Europe. Our factory is located in Istanbul, Turkey.
Each piece is knit seamlessly on Santoni machines and dyed in small batches. Every garment is unique, so no two pieces are exactly alike. We are very proud of our slow craft manufacturing process.
A GLDNspun knit blend of 81% extra fine Merino wool, 12% nylon, and 7% Spandex.
