## Long description

The nils extreme MT311 White Size L (58–61 cm) is a protective safety helmet designed to provide head impact protection for work and outdoor activities. Its white shell and adjustable fit accommodate larger head circumferences in the 58–61 cm range, offering a stable and secure wearing experience. The helmet is intended for applications where basic protective coverage, comfort, and a reliable fit are required.
Advantages
The helmet combines a hard outer shell with an internal suspension system to absorb and distribute impact forces, reducing the risk of head injury from falling objects or accidental bumps. An adjustable headband and strap system allow precise sizing within the large range, improving stability during movement. The white finish increases visibility in daylight and reflects sunlight to help moderate heat buildup during extended outdoor use.

How to use
Place the helmet on the head so that the front rim sits just above the eyebrows and adjust the internal headband until the helmet feels snug but not tight.
