BMX Helmet GIRO Quarter FS (2026) size S (51–55 cm) Matte Black

The GIRO Quarter FS (2026) size S (51–55 cm) in Matte Black is a BMX and skatepark helmet engineered for street, park, and freestyle riding. It combines a low-profile Quarter shell with Giro’s Full Spectrum protection elements to deliver core impact coverage while keeping a compact, minimalist appearance. The helmet is intended for riders who prioritize a durable shell, consistent fit in the 51–55 cm range, and a matte black finish that reduces glare and blends with common urban riding apparel.

Advantages

The Quarter FS offers a combination of lightweight construction and reinforced impact zones to protect the crown and sides of the head during jumps and slides. Its low-profile design reduces snag points on rails and ramps and provides a stable fit for street and park maneuvers. The matte finish resists obvious scuffs and maintains a discreet look. Designed with attention to ventilation and internal shaping, the helmet balances breathability with protective coverage for short intense sessions.

Suitable for

• BMX street and park riding
• Skatepark sessions and ramps
• Urban commuting with aggressive riding style
• Freestyle tricks and short downhill runs within urban environments

When it may not be suitable

This helmet is optimized for skatepark, street and freestyle use and therefore focuses on coverage and low-profile fit rather than extensive airflow or full-face protection. It may not be suitable for long-distance cycling in very hot conditions where maximum ventilation is required, nor for motorized sports or downhill racing where a full-face helmet or higher-impact rating is recommended.

Key specifications

• Intended use: BMX, skatepark, street, freestyle
• Size range: fits head circumferences 51–55 cm (size S)
• Shell type: low-profile Quarter shell
• Protection system: core impact protection with Full Spectrum elements
• Finish: Matte Black

How to use

Measure head circumference around the largest part of the head to confirm a 51–55 cm fit. Position the helmet level on the head so the front edge sits just above the eyebrows. Adjust any internal fit pads or retention system to achieve a snug but comfortable hold; straps should form a V under each ear and fasten securely under the chin with enough tension to keep the helmet from shifting. Inspect the helmet for damage before each use and replace it after significant impact.

What to consider before purchase

• Confirm head measurement falls within 51–55 cm for proper fit
• Consider desired level of ventilation versus low-profile coverage
• Check whether a matte black aesthetic matches other gear or visibility requirements
• Decide if full-face protection is needed for your specific riding style

Usage recommendations

Use this helmet for skatepark and street sessions, maintain a snug fit, and replace the helmet after any significant impact. Clean with mild soap and water and avoid solvent-based cleaners to preserve the matte finish.
