Purely Listed analysis

Merino-heavy socks and apparel; feed shows merino socks and circular wool fleece, but socks commonly use stretch/reinforcement. 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

Merino socks, base layers, accessories, and wool layers with checked blend percentages.

Material risk

Current product-listing risk terms detected: recycled nylon, nylon, lyocell, tencel. Continue to verify item-level composition, linings, trims, thread, waistbands, closures, finishes, and packaging before treating any product as plastic-free.
