Bicycle Helmet Nils Extreme MTW001-2 — Size L (58–61 cm), Green

The Nils Extreme MTW001-2 bicycle helmet in green, size L (58–61 cm), is a helmet designed for everyday cycling, commuting and recreational rides. It combines a visible finish with an adjustable fit for larger adult head sizes. The helmet aims to provide basic impact protection while remaining lightweight and comfortable for regular urban and leisure use.

Advantages

The helmet offers an adjustable fit system that helps secure the helmet on head circumferences between 58 and 61 cm, a shape and venting that balance airflow and coverage, and a bright green color that increases daytime visibility. Its construction focuses on straightforward usability: easy strap adjustments and a design suited to typical cycling positions. The size L option reduces the need for aftermarket fitting accessories for users who require a larger helmet.

Suitable for

• Everyday commuting in urban and suburban environments
• Recreational cycling and leisure rides
• Adult riders requiring a large-size helmet (58–61 cm)
• Riders who prefer a visible, green finish for better daytime visibility

When it may not be suitable

This helmet is intended for general cycling and is not specified for specialized high-impact sports such as downhill mountain biking, BMX competition, or motorized two-wheel activities. Riders seeking helmets with integrated advanced features like MIPS, built-in communication systems, or full-face protection should consider models designed specifically for those uses.

Key specifications

• Size range: Large, fits head circumferences approximately 58–61 cm
• Color: Green (visible daytime finish)
• Intended use: Everyday cycling, commuting, recreational riding
• Fit system: Adjustable retention and chin strap for customized fit
• Design focus: Lightweight construction with ventilation and coverage suitable for urban/leisure cycling

How to use

Place the helmet on the head so it sits level and covers the forehead without tilting back. Adjust the retention system until the helmet feels snug but comfortable around the head. Fasten and adjust the chin strap so it fits closely under the chin and allows about one or two fingers of space. Regularly inspect the helmet for visible cracks, compression of foam, or damaged straps and replace it after any significant impact or according to manufacturer guidance. Clean the helmet surface and straps with mild soap and water and avoid solvents or abrasive cleaners.

What to consider before purchase

• Measure head circumference to confirm the 58–61 cm range matches your size
• Decide whether you need additional features (e.g., MIPS, extra ventilation, integrated lights)
• Consider visibility needs: the green finish improves daytime visibility but may not replace reflective elements for night riding
• Check compatibility with eyewear, glasses, and any cycling accessories you commonly use

Usage recommendations

Use this helmet for daily commuting and leisure cycling where a large-size protective helmet with a visible finish and straightforward adjustment is appropriate. Replace the helmet after any significant impact and follow care instructions to maintain protective properties.
