Which factor intensifies the bargaining power of suppliers in the performance-based apparel market?

The bargaining power of suppliers is strengthened in the performance-based apparel market when they offer proprietary fabrics that have superior features. This is because such materials can provide unique advantages that enhance the performance of clothing, such as increased durability, breathability, moisture-wicking properties, or other specialized characteristics that are not easily replicated.

When suppliers possess proprietary fabrics, they can dictate terms more effectively since manufacturers are more reliant on these unique materials to differentiate their products in a competitive marketplace. It creates a scenario where the suppliers hold a significant advantage, as manufacturers may not have alternative sources for these specialized fabrics and may be willing to pay a premium for them. This scenario leads to an increase in suppliers' bargaining power as they can influence prices and conditions due to the uniqueness and desirability of their offerings.

In contrast, factors like low-quality fabric availability or high demand for generic apparel do not create a strong supplier advantage. Low switching costs for manufacturers also reduce the leverage suppliers might have, as manufacturers can easily change suppliers without incurring substantial losses. Therefore, the presence of proprietary fabrics with superior features is the key element that intensifies supplier bargaining power in this context.
