Organic Underwear Manufacturing
FOCS is a organic underwear manufacturer producing certified organic cotton underwear — boxers, briefs, tights and base layers — under our own GOTS licence. Underwear is the most skin-sensitive category in apparel: that is why we hold OEKO-TEX 100 Class I, the baby-grade standard, for everything we ship. Your brand gets GOTS transaction certificates and test reports that survive both retailer audits and customer scrutiny.
Underwear sits against skin all day, in the warmest and most absorbent conditions — which is exactly where chemical residues matter most. Conventional underwear can carry azo dyes, formaldehyde finishes and nickel trims. FOCS underwear is produced under GOTS (which restricts chemical inputs at every step) and tested to OEKO-TEX 100 Class I, the grade designed for baby products. Marketing 'organic underwear' without these documents is a claim waiting to be challenged.
Our knit background gives us a structural advantage in underwear: the same fine-gauge machines and elastic expertise that produce our certified socks create waistbands, cuffs and seamless-adjacent constructions with consistent recovery after 50+ washes — the failure point of cheap underwear programs. We test wash fastness and elastic recovery on every new style before bulk approval.
For brands, underwear is a high-repeat-purchase category: customers who trust your first pair buy multi-packs and subscriptions. That trust is built on certifications that verify — which is why we issue GOTS TCs per order and keep Class I test reports on file for your product pages and retailer submissions.
