Buying Guide

Prioritize fit and adjustability

A helmet that adjusts securely around the head is more important for bouldering falls than nominal weight — look for models with reliable cradle systems and easy-to-use tighteners

Choose between ABS shell and foam styles

ABS-shell helmets offer durable outer protection and can be lighter for repeated gym use, while foam-construct helmets may provide different impact characteristics suited to trad or multi-pitch climbing

Consider ventilation and session length

Ventilation affects comfort during intense projects or long gym sessions; vented models reduce heat buildup but may slightly change impact coverage

Balance weight versus coverage

Lighter helmets reduce neck fatigue during dynamic moves, but ensure they still provide sufficient coverage for the forehead and occiput

Check compatibility and accessory features

Look for headlamp clips, helmet-compatible eyewear fit, and washable liners — small features that improve day-to-day usability for bouldering and gym climbing
