Purely Listed analysis

A legitimate natural-fiber and sheepskin specialist with B Corp certification and strong UK manufacturing, but the catalog includes lyocell, mixed fabrics, footwear components, and regenerated fibers. Good On You’s broader independent rating is only “It’s a Start.” No brand-wide plastic-free claim is assumed; sewing thread, elastic, linings, closures, finishes, and trims still require product-level confirmation. The score is brand-wide: an excellent 100% natural-fiber item does not make a mixed catalog synthetic-free.

What to verify before buying

Confirm the exact product page and care label for fiber percentages, sewing thread, elastic, labels, linings, closures, finishes, coatings, and packaging. “100%” normally describes the main fabric unless the brand provides a full component bill of materials.

Best for

Wool knitwear, sheepskin outerwear and slippers, leather footwear, and selected linen or organic-cotton pieces.

Material risk

Verify every composition, especially footwear soles/adhesives, linings, zippers, and blended garments. B Corp status does not mean products are plastic-free.
