Why should jeans not be worn as protective riding gear?

Jeans are not considered adequate protective riding gear primarily because they do not provide sufficient abrasion resistance in the event of a fall or accident. While they may be durable for everyday wear, traditional denim lacks the specialized materials and reinforcement found in motorcycle-specific gear. A dedicated motorcycle riding suit or pants are often crafted from materials designed to withstand the rigors of riding and accidents, including features like reinforced stitching, ballistic nylon, or Kevlar inserts that provide better protection against abrasion and impact.

In contrast, while the other options may point to some practical issues related to comfort or style, they do not address the critical safety concern of inadequate protection that jeans offer compared to purpose-built riding gear.
