Should the buckle of a helmet strap be adjustable?

The buckle of a helmet strap should indeed be adjustable to allow for a secure and comfortable fit. An adjustable buckle enables users to customize the size of the helmet to their head shape and size, which is essential for safety. A properly fitted helmet is less likely to slip off or move during an impact, providing maximum protection to the wearer. Comfort is equally important, as a helmet that does not fit well can cause distractions or discomfort, potentially leading to unsafe situations.

Without the ability to adjust the buckle, wearers might struggle with an overly tight or loose fit, compromising both safety and usability. This adjustability is a key feature in helmet design and is vital for ensuring that the helmet meets safety standards effectively.
