Which fabric shows high thermal retention and poor tenacity, typically used for suits and outerwear?

• A. Herringbone
• B. Denim
• C. Serge
• D. Surah

Answer: (A)

Fabrics used for suits and outerwear that rely on wool fibers gain their warmth from the fiber’s natural insulation and from a dense, tightly woven structure. Herringbone is a classic wool fabric with a twill pattern that creates a compact surface and traps air, giving it good thermal retention. At the same time, wool fibers in this weave provide decent—often moderate—tenacity, which is enough for garments but not the highest strength you’d see in specialty performance fabrics. That balance—warmth from the wool and a sturdy yet not overly aggressive strength from the twill weave—makes it a typical choice for suits and outerwear. In comparison, denim is very strong but not chosen for warmth-focused outerwear; surah is light and glossy with less insulation; serge is durable and common for suits but not specifically defined by high warmth.
