Buying Guide
- Safety technology: Look for MIPS, dual-density EPS, and, where applicable, high-speed EPP or low-speed EPS coverage. These layers work together to manage energy across different impact scenarios.
- Ventilation and comfort: A high-quality MTB helmet should include ample vents (14 or more is common) and a comfortable liner to maintain airflow and reduce fatigue on hot days.
- Fit and adjustability: A 360-degree retention system, rear height adjustment, and adjustable visors help you tailor the helmet to your head shape and riding style. Some models also use quick-release buckles for convenience.
- Visor design and practicality: A screwless or easily adjustable visor adds versatility for shade in varied lighting without compromising safety or weight.
- Sizes and youth options: MTB gear comes in youth OSFA or adult MD/LG sizing. Always verify measurements and consider growing room for younger riders.
- Apparel considerations: Jerseys should be lightweight, breathable, and moisture-wicking; look for skin-friendly fabrics that resist chafing and dry quickly on long rides.
- Durability and warranty: Check warranties (some Troy Lee helmets include multi-year coverage) and the durability of fasteners and buckles to ensure long-term value.
- Maintenance and care: Follow cleaning directions for helmets and jerseys; avoid harsh chemicals and ensure proper drying to maintain performance and fit.
