Plastic-free sweater, ranked by what they're actually made of.

5 sweater scored 0–100 for plastic content and ranked lowest-plastic-first. Scores come from listed material evidence where it exists; incomplete evidence is marked ~ and never presented as a verified plastic-free result. Every score links to its full breakdown.

How this ranking works

Each product's score is the percentage-weighted plastic share of its listed fiber composition — polyester weighs 100, viscose 10, cotton 0, with every weight public. Only products whose material evidence passed a completeness audit are ranked here; a low score with incomplete evidence is a conservative estimate, not proof of a plastic-free product.

Common materials in sweater

• Wool — 0/100. Zero plastic, naturally technical — warm, breathable, odor-resistant.
• Nylon (Polyamide) — 100/100. The original synthetic fiber, spun from crude-oil-derived polyamide.
• Polyester — 100/100. The world’s most-worn plastic. Made from PET — the same polymer as soda bottles.
• Cotton — 0/100. Zero plastic. Water-hungry, but fully biodegradable.
• Viscose (Rayon) — 10/100. Plant cellulose, heavily processed. Not petro-plastic; biodegrades.
• Elastane (Spandex) — 100/100. The stretch in your stretch. Polyurethane-based, in nearly everything fitted.
