SMK Alterra Helmet - MT.ANTHRACITE

The SMK Allterra is a dual-sport adventure helmet designed for riders who move between sealed roads and unsealed tracks. Its full-face shell and adjustable peak suit both touring routes and gravel exploration without requiring a helmet change.

The matte anthracite finish is understated and practical — minor surface marks are far less visible than on gloss coatings. The removable interior keeps the helmet fresh across long days in the saddle, and the size run from XS through to 2XL covers a broad range of riders.

Clean the outer shell with mild soap and warm water on a soft cloth; avoid petroleum-based solvents, harsh detergents or abrasive cleaners, which can degrade the shell and graphics.
Clean the visor by first rinsing with warm water to loosen grit, then wipe gently with a soft damp cloth — never wipe a dry visor as trapped particles will scratch the lens.
Remove the interior liner and cheek pads periodically for washing; hand wash in lukewarm water with mild detergent and allow to air dry completely before refitting.
Inspect the chin strap and retention buckle regularly for fraying, cracking or wear; replace if compromised.
Store the helmet in a cool, dry location away from direct sunlight, fuel, oil and chemical fumes — these degrade EPS foam and shell materials over time.
Do not paint, apply solvent-based adhesives to, or drill the outer shell as any modification may weaken structural integrity.
Replace the helmet after any significant impact even if no external damage is visible — EPS foam crushes to absorb energy and cannot recover its protective capacity.
Adjust or remove the peak for sustained high-speed road riding to reduce buffeting and wind noise.
