Which helmets for spelunking are best?

While spelunking can be considered dangerous, responsible decision-making and appropriate safety gear help keep the likelihood of a spelunking accident low. If you want to get out and explore the caves near you, make sure you have a helmet like the Petzl Boreo Caving Helmet to keep you safe.

What to know before you buy a helmet for spelunking


Besides getting the correct size, you want a low-profile helmet that stays squarely on your head and doesn’t ride high. This will allow you to safely get in and out of tight spaces without worrying about your helmet getting caught as you crawl through caves and tunnels.


There’s nothing less comfortable than lugging a heavy device on your head as you explore. No, you won’t find ultralight options (though some may be lighter than your bike helmet). There are, however, lighter choices that will keep you both safe and comfortable.


The most important thing in a good spelunking helmet is finding one that won’t roll off. When you purchase your helmet, have a friend try to roll it off the front and back of your head. If you can roll it off, that helmet doesn’t fit you properly. You want to make sure to test this out ahead of time before trying your luck in a cave.

What to look for in a quality helmet for spelunking

Chin strap

Any good spelunking helmet will have a chin strap that attaches at four points. This looks like a V shape around each ear that then moves to attach to the other under your chin. These four points of contact make sure your helmet stays secure to your head if you get caught in a tight spot.

Headlamp mount

It should go without saying, but caves can be pretty dark. Make sure your helmet has a headlamp mounting plate. They’ll often have mounting plates in the front and back of the helmet, which can be especially useful.

High-quality materials

Your best bet is to go with plastic. Fiberglass is another option; however, a high-quality plastic can take a few more hits without cracking. 

How much you can expect to spend on a helmet for spelunking

The average spelunker can use a helmet that costs between $50 and $100.

Helmet for spelunking FAQ

Do I need to use a spelunking-specific helmet?

A. No, but it helps. If you don’t have a spelunking helmet available, a climbing helmet can be a good substitute. You could probably use a mountaineering helmet as well.

What is a good safety certification for a spelunking helmet?

A. In the U.S., the UIAA certification means a helmet is high quality. Europe has a set of standards called the CE standards, but they’re a bit less comprehensive. If getting a European brand helmet, look for the CE EN12492 certification. High-quality helmets like the Petzl brand have the CE EN12492 certification, and it’s a standard you can trust.

What is the lifespan of a helmet?

A. You can get about a decade’s worth of use from a helmet, assuming no major incidents. If you do take a blow to the helmet, you’ll want to look at getting a new one. Even if you walk away fine and the helmet shows no sign of impact, the protection may be weakened.
