Climbing helmets are designed to protect you against several common climbing scenarios: rocks or hardware get kicked loose above you, you fall off and swing into a wall or you hit your head on an overhang.
All helmets must meet industry standards for impact protection, with the standard for overhead protection being greater than the side-protection standard EN 12492.
Hard shell Helmets
This type of durable, traditional lid features an extra-hard outer shell, typically ABS plastic, that’s paired with a strap suspension system and a thin foam liner.
Other terms for these helmets are suspension helmets and hybrid helmets.
This type of helmet offers two primary advantages:
Shelled Foam Helmets
This lightweight style features a thick layer of impact-absorbing polystyrene or polypropylene foam protected by a thin polycarbonate shell. Impact forces are dissipated via deformation. This type of helmet offers two primary advantages:
CHOOSING HELMETS BY CLIMBING TYPE
Mountaineering and multi-pitch trad climbing:
When you’re hauling a lot of gear and wearing a helmet for long periods of time, low weight and ample ventilation are important. So consider a shelled foam helmet.
Also, choose a bright helmet color for mountaineering. Hard to see conditions are always a possibility and you want your team members to be able to spot you.
Because you will be vulnerable to a lot of falling debris, look for a shelled-foam model with minimal ventilation area. You don’t need much cooling, and you don’t want a lot of openings to let in whatever might rain down on you.
Warm-weather sport climbing:
Look at shelled foam models with the greatest number of ventilation openings.
Cool-weather and single-pitch sport climbing:
Because you can take the helmet off while waiting your turn to climb or belay, you can choose to trade the comfort of a shelled foam model for the durability and affordability of a hardshell.
Protection from rockfall and dropped gear is a concern, so it’s important that you also wear a helmet while belaying. No special helmet is required: Simply wear what ever you brought for climbing.
Gym rules and liability waivers will dictate whether a helmet is required. Because rockfall isn’t a concern, though, a cool, lightweight shelled foam helmet is the logical choice if you’re required to wear one.
Additional Climbing Helmet Considerations
Almost all helmets have headlamp clips now, so it’s less of a consideration. If you plan on long climbs with predawn starts or post-sundown finishes, these clips are essential.
CLIMBING HELMET FIT
Even when friends or reviewers suggest that one helmet is the best, it won’t be right for you if it doesn’t fit correctly. If you can’t get a good fit with your chosen helmet, you need to try another model. The best way to assess fit is to try on different helmets in a climbing specialty store.
Check for a secure fit:
Start by placing the helmet squarely on your head, with the front rim straight across your forehead. After you adjust the fit, but before you buckle the chin strap, shake your head from side to side and tilt your head slightly back. The helmet should remain snug.
Check and adjust chin straps:
After they are buckled you should have no slack and the front and rear straps should form a “Y” around each of your ears.
Check the ease of adjustment:
Play with the adjustment system to see how intuitive you find it and how easy it is to fine-tune the fit. Ease of adjustability is key for cold conditions because you need to readjust the fit to accommodate a skullcap underneath the helmet.
CLIMBING HELMET LIFESPAN
Retire any helmet that’s dented, cracked or damaged—including the straps. Even in the absence of visible damage, retire yours after any incident where you think to yourself, “I would have been seriously messed up if not for my helmet.”
Do these checks before every climbing trip:
If the answer to any of these questions is “no,” then get a new helmet. In addition, you should stow your helmet inside a climbing bag to protect it from banging against hard surfaces, which makes it vulnerable to chipping and cracking. Even if it’s never impacted, retire a helmet within 10 years. The sun’s UV rays slowly degrade materials, so if you climb frequently, cut this lifespan time in half.
