## Long description

The Cairn R Dust II protective helmet in size M (55–58 cm) is a multi-purpose head protector suitable for cycling, urban mobility and light occupational tasks. The helmet combines a fitted outer shell with an adjustable retention system to deliver a secure, comfortable fit for everyday use. Its design focuses on impact protection and stability while remaining compact and lightweight for daily wear.
Advantages
The Cairn R Dust II offers reliable impact protection through a shaped shell and energy-absorbing liner that reduce the force transmitted to the head. The adjustable retention ring and chin strap allow quick, precise sizing within the 55–58 cm range to maintain stability during movement. Ventilation channels and a low-profile design help balance airflow and protection without adding unnecessary bulk. The helmet is compatible with common urban accessories and can be used in mixed activities where moderate impact protection is required.
Suitable for
 Commuting and city cycling
 Electric scooter and micromobility use
 Leisure cycling and short urban rides
 Light occupational tasks requiring basic head protection
 School runs and family outings
Key specifications

 Retention system: adjustable rear dial for secure fit
 Straps: adjustable chin strap with fast-release buckle
 Ventilation: integrated vents for airflow and comfort

How to use
Place the Cairn R Dust II on the head so that the front edge sits just above the eyebrows and the shell covers the back of the head. Rotate and tighten the rear retention dial until the helmet feels snug but comfortable. Adjust the side straps so they form a V-shape around the ears and fasten the chin strap, leaving enough room to fit one or two fingers between the strap and the chin. Before each use, check that the helmet is secure, straps and buckle work correctly, and there are no visible cracks or damage to the shell or liner.
Usage recommendations
Use this helmet as primary protection for low- to medium-risk urban activities. Replace the helmet after any significant impact, after visible damage, or according to manufacturer guidance. Keep the helmet clean and store it away from direct sunlight and extreme heat to preserve materials and fit.
