Care

Machine wash cold on normal cycle. Tumble dry low.

SUSTAINABILITY

Built on CiCLO® biodegradable fiber.

CiCLO® is built into our recycled synthetics to do two things: shed fewer microplastics in wear and wash, and biodegrade rather than linger. Independent testing shows CiCLO treated fibers biodegrade in under four years — so they don’t add to long-term microplastic pollution.

Certified by ECO PASSPORT by OEKO-TEX®.
