Fordeler

• ASTM F1952 downhill certification on an open-face trail helmet; offers higher impact coverage than typical EN1078-only models
• Dual-density EPS + EPP/EPO liner for improved energy management across impact speeds
• Leatt 360° Turbine rotational-impact system integrated without adding a slip liner bulk
• Extended coverage at temples and occipital area
• Fidlock magnetspenne enables one-handed operation with gloves
• Breakaway, adjustable visir designed to reduce rotational forces in a crash
• Good vent layout (18 porter) with internal MaxiFlow kanaler for sustained airflow
• Dri-Lex fukttransporterende, vaskbart og luktresistent innerfôr
• Goggle/sunglasses dock under visir for sikker oppbevaring
• Broad size range with multiple safety certifications (EN1078, CPSC 1203; ASTM F1952; some markets NTA 8776)

Ting å vurdere

• Heavier than several premium trail/open-face alternatives; can feel warm on slow, steep climbs
• Ventilation is good but not class-leading versus the most ventilated trail helmets
• Fit tends toward a slightly round/neutral head shape; long-oval heads may experience pressure points without pad tweaks
• Visor range and goggle parking clearance can be limited for some users
• Rotational-impact performance claims (percentage reductions) are manufacturer-stated; limited independent validation specific to this model
• Spare pad/part availability can be region-dependent

Oppsummering & anbefalinger

Leatt MTB AllMtn 4.0 is a robust, open-face trail/enduro helmet emphasizing safety credentials (ASTM F1952, multi-density liner, 360° Turbine) and practical features (Fidlock, breakaway visor, washable liner). It trades a bit of weight and top-tier ventilation for increased coverage and certification. Fit is slightly round/neutral, and visor clearance may not suit all eyewear setups. Well-suited to riders prioritizing coverage and certification in technical terrain, with minor compromises in airflow and weight.

Bruksområder & tips

Best suited for trail/all-mountain og light enduro riding where higher impact certification and extended dekning are prioritized over ultralav vekt og maksimal kjøling. Also appropriate for e-MTB use in markets where NTA 8776 is supplied. Riders with round to neutral hodeform will likely achieve the most secure passform.
