Boreo Climbing Helmet

What Our Gearhead® Experts Are Saying:

"The Boreo is the helmet I hand to people who want something tough and no-fuss. The ABS shell handles the kind of abuse that happens when a helmet lives in a pack — getting sat on, dropped, scraped against rock — and the hybrid foam system means it's doing real work if something actually hits you. The fixed vents aren't going to keep you as cool as a foam-only lid on a hot day, but the tradeoff is a shell that holds up better over time. Rear slider fit adjustment is straightforward, and the headlamp clips are solid."

Who It's For

Climbers and outdoor adventurers who want durable, versatile head protection

The Boreo is a strong fit for beginner to intermediate climbers who want a reliable helmet that handles a range of activities — sport climbing, trad, via ferrata, canyoneering, and caving all fall within its certified use range. It's also a practical choice for guides, instructors, or anyone who puts a helmet through heavy regular use and needs a shell that resists dings and dents over time. Climbers prioritizing minimal weight above all else will find lighter options, but anyone who values durability and coverage will be well served here.

What It's For

Rock climbing, via ferrata, canyoneering, and caving

The Boreo is a versatile multi-activity helmet certified for climbing, via ferrata, caving, and canyoneering. The extended back provides more coverage than most sport-oriented lids, which matters in environments where rockfall can come from unpredictable angles. Fixed vents keep air moving during sustained effort, and the integrated headlamp clips make it practical for approaches, cave systems, or any objective that runs into low light.

Why We Like It

Tough ABS shell, dual-foam impact system, and a hybrid build that stays low-profile

The hybrid construction is the key design choice here: an ABS outer shell handles surface abrasion and everyday pack abuse, while the EPP and EPS foam liner works underneath it to absorb impact energy if the helmet takes a real hit. EPP foam handles repeated lower-energy impacts without losing its shape, while EPS manages higher-energy single impacts — together they cover more of the impact spectrum than either foam alone. The extended rear coverage addresses a gap that shorter helmets leave exposed, and the rear slider keeps fit adjustment simple without requiring tools or complicated ratchet systems. Headlamp clips are molded into the shell so there's no separate attachment to lose.
