## Long description

GIRO Quarter FS — size S (51–55 cm) in Matte Dark Shark is a protective bicycle helmet developed for urban riding, BMX and light trail use. The helmet has a low-profile shell and multi-density impact protection designed to manage different impact energies while keeping overall volume compact. Internal padding and an adjustable fit system provide stable positioning and comfort during everyday rides and sessions in skateparks or mixed-terrain routes.
Advantages
The low-profile shell reduces bulk and improves rider mobility while still offering coverage where it is most needed. Multi-density impact protection helps absorb and dissipate forces from varied impacts. Internal padding enhances comfort and sweat management, and the adjustable fit system allows precise sizing within the 51–55 cm range for reliable, secure fit. The matte finish provides a subdued aesthetic that resists glare and looks consistent with urban and action-sport styles.
Suitable for
 Urban commuting and city cycling
 BMX and skatepark sessions
 Light off-road or dirt jump trails
 Short group rides and everyday cycling
Key specifications
 Size range: S, fits head circumference 51–55 cm
 Shell type: low-profile, compact design
 Impact protection: multi-density construction for varied-energy impacts
 Fit system: adjustable retention mechanism for precise positioning
 Comfort: internal padding for cushioning and moisture control

How to use
Place the helmet level on your head so the front edge sits just above the eyebrows. Adjust the retention system until the helmet feels snug but not tight; the helmet should not move significantly when you shake your head. Fasten and adjust the chin strap so it forms a V shape under each ear and secures comfortably under the chin. Replace internal pads as needed to maintain comfort and proper fit. Inspect the helmet for visible damage after any significant impact and follow manufacturer guidance for service life and replacement.
Usage recommendations
Use the GIRO Quarter FS for city commuting, BMX park sessions and light trail riding where a compact, adjustable helmet is preferred. For maximum protection, ensure correct sizing (51–55 cm for size S), secure strap fastening, and replace the helmet after any major impact or according to the manufacturer's recommended service life.
