Convertible Mountain Bike Helmet with Detachable Chin Guard

Engineered for trail riders, commuters and enduro enthusiasts, this convertible mountain bike helmet from Kalsten combines the protection of a full-face design with the comfort and breathability of an open-face helmet. The removable chin guard converts the helmet in seconds, giving you flexible coverage for technical descents and fast, ventilated climbs.

Key Features

• Convertible design: Quick-release detachable chin guard lets you switch between full-face protection and an open-face trail helmet without tools.
• Impact management: Durable polycarbonate outer shell bonded to an energy-absorbing EPS liner for reliable shock dispersion on impact.
• High-flow ventilation: Multiple strategically placed vents and internal air channels keep airflow moving to reduce heat buildup on long rides.
• Adjustable fit system: Smooth micro-adjust dial and padded retention cradle deliver a secure, customizable fit for a wide range of head shapes.
• Comfort-focused padding: Removable, machine-washable liners and soft chin strap pads provide all-day comfort and easy cleaning.
• Lightweight construction: Balanced weight distribution reduces neck fatigue while maintaining robust protection for trail and urban riding.
• Integrated visor: Low-profile visor shields glare and debris while preserving airflow and sightlines on technical trails.
• Secure strap system: Quick-release buckle and reinforced straps keep the helmet stable during aggressive maneuvers.

Why Riders Choose This Helmet

This versatile helmet is ideal for riders who want one helmet for multiple disciplines. Use the full-face configuration for downhill and technical sections when extra facial protection is needed, then remove the chin guard for lighter cross-country rides or urban commutes. The combination of ventilation, adjustable fit and washable comfort liners makes it a practical choice for frequent riders seeking performance and convenience.

Use & Care

• Detach chin guard using the quick-release points, follow the included guide for secure reattachment.
• Remove interior pads for washing and air dry to maintain hygiene and comfort.
• Inspect straps and shell regularly for signs of wear and replace after significant impact.

Optimize your ride with the convertible mountain bike helmet from Kalsten—a flexible, breathable and protective solution for every trail and commute.
