Which fabrics suit winter clothing?
Winter clothing needs cover and, often, a cloth that traps still air. Wool suitings, coating cloths, and denser knits are usual candidates. A high GSM number alone does not prove warmth, and a lined lighter cloth can wear warmer than a heavy open weave.

- Insulation is structure plus layering, not a fiber trophy.
- Read published weight when it exists.
- Do not treat fleece, wool, and denim as interchangeable.
What changes the shortlist
A coat, a shirt, and a base layer do not share a GSM. Start from the garment.
Stretch and hand still matter for trousers. A dense cloth that does not recover can fail a fitted brief.
