RAY OF HOURS garments are designed to last. We use natural fibres — silk, cotton, cashmere — that are fully biodegradable when free of synthetic blends. When a garment reaches the end of its life, we encourage responsible disposal: donate, resell, or return to a textile recycling facility. Natural fibre garments should never be sent to landfill where conditions prevent biodegradation.

This product passport is reviewed and updated regularly to reflect current production and material sourcing. Last updated: September 2026.
