What is the main purpose of using arm guards in archery?

Arm guards are primarily designed to protect the arm from the bowstring during the release phase of shooting. When the bowstring is released, it snaps back and can make contact with the archer's forearm, particularly if the shooting form is not optimal or the bow is drawn with a high draw weight. This contact can cause discomfort, potential bruising, or even injury.

By wearing an arm guard, archers can shield their forearms from this impact, allowing them to focus on their technique without the distraction of pain or injury. While there are benefits to other options listed, such as comfort or maintaining better shooting form, the fundamental purpose of an arm guard is to provide protection from the bowstring, ensuring a safer and more enjoyable archery experience.
