Wash care Thanks to its antimicrobial properties which make it resistant to odour-producing bacteria, your merino activewear will not need to be washed as regularly. We recommend quick washes in the sink with cool water, and spot cleaning any stains. You can refresh your garment between washes by gently steaming it. Hand wash* with gentle detergent, wool, or baby shampoo Lay flat to dry on a towel Apply a gentle iron with a slow steam Do not tumble dry *Why we use hand wash only merino wool Machine-washable merino wool is treated with a heat-resistant plastic, which cracks as it is washed and tumble dried. Aggressive washing damages merino, causing the wool to pill more, lose its shape and appear worn quicker than caring for hand wash only fibres. Overall, choosing hand wash only merino wool means items last longer and they’re more environmentally friendly. Made in our factory in India using the latest Japanese knit-ting technology.
