What is the primary purpose of fiberglass arrows?

The primary purpose of fiberglass arrows is indeed their durability and ruggedness, which makes them suitable for various conditions and repeated use. While they are often appreciated for their resilience compared to other materials, this also plays into their design being suitable for beginners or casual archers.

Fiberglass arrows are typically heavier than other materials, which actually aids in better penetration of the target upon impact. Their design allows them to withstand the impacts associated with misses and rough handling in the field. As a result, fiberglass arrows maintain structural integrity during use, making them a practical choice, especially for those learning the sport.

The other options, while they may partially represent characteristics of fiberglass arrows, do not capture their primary purpose. For instance, although cost-effectiveness might be true for some users, the primary focus is more on how robust and capable they are for reliable performance in various shooting conditions. Similarly, while lightweight design is a feature in other types of arrows, fiberglass arrows typically do not emphasize this trait.
