Mountain Bike Helmets
Mountain bike helmets are designed to provide impact protection, extended coverage and ventilation for off-road riding. Within this category, the two primary styles are full face helmets and trail helmets, each suited to different disciplines, terrain and rider preferences.
We stock mountain bike helmets from Abus, Fox, Smith and Giro, with models suitable for downhill, enduro, trail and cross-country riding.
Full Face Mountain Bike Helmets
Full face helmets provide maximum coverage, including a fixed chin bar for additional facial protection. They are commonly used for:
- Downhill (DH) riding
- Bike park riding
- Enduro racing (especially technical stages)
- Aggressive trail riding
Key features:
- Extended coverage around the jaw and lower face
- Reinforced chin bar for high-speed impact protection
- Adjustable visor for goggle compatibility
- Compatibility with action camera mounts (chin or peak)
- Removable and washable internal padding
Full face helmets prioritise protection over airflow. However, many modern designs now incorporate:
- Large intake and exhaust ports
- Internal channelling for airflow
- Lightweight shell construction
For maximum ventilation in gravity-focused riding, look for full face helmets with multiple front vents, open chin bar airflow, and internal air channels designed for enduro racing rather than pure downhill use.
Trail Mountain Bike Helmets
Trail helmets are the most versatile and widely used style of mountain bike helmet. They feature a traditional open-face design and are suitable for:
- Trail riding
- Enduro riding
- Cross-country (XC) riding
- Leisure cycling
- Urban and city riding
Key features:
- Extended rear coverage compared to road helmets
- Lightweight in-mould construction
- Adjustable peak
- Action camera compatibility (peak-mounted)
- Removable, washable padding
Trail helmets generally offer the highest levels of ventilation due to:
- Larger vent counts
- Open shell designs
- Internal airflow channels
For riders prioritising airflow during long climbs, summer riding or cross-country use, trail helmets typically provide the most ventilation.
Impact Protection Systems
Modern mountain bike helmets incorporate advanced impact management systems designed to reduce rotational and linear forces during a crash.
MIPS (Multi-directional Impact Protection System)
MIPS is a low-friction layer inside the helmet that allows controlled movement between the head and helmet during angled impacts.
- Designed to reduce rotational forces
- Integrated between the liner and padding
- Found across a wide range of trail and full face helmets
Zonal KOROYD® Coverage (Smith)
Smith helmets may feature Zonal KOROYD®, a honeycomb-like energy-absorbing structure integrated into specific areas of the helmet.
- Designed to absorb impact energy more efficiently than standard EPS foam alone
- Provides targeted protection in key impact zones
- Combined with MIPS in selected models
When comparing helmets, check whether the model includes MIPS, KOROYD®, or a combination of both systems.
Ventilation and Comfort Features
Premium mountain bike helmets focus on both protection and comfort for extended riding.
Ventilation
- Trail helmets generally offer the most airflow
- Enduro-focused full face helmets provide balanced ventilation and protection
- Downhill helmets prioritise coverage and structural integrity
Look for:
- Multiple intake and exhaust vents
- Internal airflow channelling
- Lightweight shell materials
Fit and Retention
Most high-quality helmets now include:
- Fidlock magnetic chin strap buckles for quick fastening and release
- Adjustable retention systems for precise fit
- Height-adjustable cradles
Hygiene and Maintenance
- Removable and washable internal pads
- Moisture-wicking liners
- Replaceable cheek pads on full face helmets
These features improve long-term comfort and allow easier maintenance.
Action Camera Compatibility
Many mountain bike helmets are compatible with action cameras:
Some helmets include flat peak sections designed to provide a secure surface for adhesive camera mounts. Always follow manufacturer guidance when attaching accessories.
Choosing the Right Mountain Bike Helmet
When selecting a helmet, consider:
- Riding discipline (downhill, enduro, trail, XC)
- Required level of coverage
- Ventilation requirements
- Impact protection systems (MIPS, Zonal KOROYD®)
- Fit and retention system
Full face helmets are suited to high-speed, technical riding where maximum coverage is required. Trail helmets provide versatile protection with increased airflow for climbing, mixed terrain and everyday use.
