Merino-led performance brand with strong aggregate fiber disclosure and ZQ sourcing, but individual products range from nearly all-merino to nylon/elastane/TENCEL blends.
Merino-led performance brand with strong aggregate fiber disclosure and ZQ sourcing, but individual products range from nearly all-merino to nylon/elastane/TENCEL blends. 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.
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.
Merino tees, base layers, underwear, and outdoor apparel when blend percentages are acceptable.
Icebreaker reports 98.3% plastic-free fabric composition for its 2025 collection by weight, explicitly excluding trims and decorations. Product-level variation remains large: one current ZoneKnit tight is 39% merino, 36% TENCEL, 19% nylon, and 6% elastane.
Full-audit score retained at 72. Breakdown: 33/40 materials, 9/20 plastic-free construction, 10/15 natural-fiber catalog focus, 7/10 certifications, and 13/15 transparency and independent evidence.
Re-audited 2026-08-02 using the current official catalog and product evidence, then cross-checked against directory.goodonyou.eco. Independent sources were used to corroborate composition, certifications, construction, catalog scope, or transparency; unsupported component claims were treated as unknown. Evidence confidence: Medium-high.
