Solid colored knit ties are textured neckties made of wool, cashmere, or both. Complicated patterns are difficult to incorporate because of the complex construction of the material that is why knit ties are mostly available in solid colors only.
Wool neckties are soft, thick ties. They have insulating properties making them suitable for winter. Lots of regular wool ties nowadays are designed, not only for winter and casual wear, but also for formal and corporate wear.
