Natural modal fibers are known for their ultra soft textures. Micro-Modal is an even finer version, so washing on too harsh a cycle can reduce its properties and longevity long term. We recommend separating lights from darks and washing separately. Machine wash in warm water, preferably on the delicate cycle, and don’t use bleach or fabric softener. Tumble dry on the lowest heat setting and remove as soon as they’re dry. During testing with SGS, an independent testing service, we got virtually no shrinkage in their most rigorous hot washing test. Regardless, we do not recommend using the hot setting.
