The full product-by-product breakdown for Older Brother is being added.

How we scan. Every figure on this page comes from the Throne Standard scan: we read the fibre composition off each live product on the brand’s own site, style by style, and count only single-fibre plant cloth (cotton, linen, hemp) as natural. Animal fibres such as wool, silk and cashmere and plastic-based synthetics such as polyester, nylon and elastane sit outside the plant-fibre figure, and regenerated fibres such as viscose, bamboo, modal and Tencel are counted as semi-synthetic. Percentages are calculated over the styles that state a composition; anything unlabelled is shown separately.
