Half helmets are the most polarizing category in motorcycle gear. Riders who wear them value the open-air experience, peripheral vision, and low weight that no other helmet type provides. Safety advocates point out — correctly — that half helmets leave the face, chin, and jaw unprotected, which are the most frequently impacted areas in motorcycle crashes. Both positions are factual. This guide does not argue the debate. It covers what DOT-certified half helmets do well, what to look for if you have decided to ride in one, and how to distinguish a genuine certified helmet from a novelty shell that offers no legal protection and no meaningful impact absorption.
What DOT Certification Means for Half Helmets
A DOT FMVSS 218 certified half helmet has passed the same impact absorption and penetration resistance tests that full-face helmets pass — for the areas it covers. That means the crown, upper skull, and the sides of the head above the ear line have been tested against flat and hemispherical anvils at prescribed impact speeds, and the helmet has demonstrated that it keeps transmitted forces below the standard's threshold.
What DOT certification does not change is the coverage footprint. A half helmet leaves the face, chin, jaw, ears (in most designs), and the lower rear of the skull exposed. No certification makes those areas safer because the helmet is simply not present there. Understanding this is essential: DOT on a half helmet means the part of your head that the helmet covers is protected to a measurable standard. Everything outside that footprint is unprotected.
The Picks
Bell Pit Boss
The Pit Boss is Bell's flagship half helmet and it earns its reputation through fit, finish, and features that budget half helmets do not match. The TriMatrix composite shell is lighter than the polycarbonate competition while meeting DOT standards. A retractable internal sun shade drops down behind the brow with a lever — no snap-on visor to fumble with at a stoplight. The speed-dial fit system lets you adjust the inner diameter on the fly for a secure hold without the helmet feeling like it is squeezing your temples. The liner is removable and washable. For a half helmet, the Pit Boss offers more adjustability, better materials, and a cleaner aesthetic than anything else in the category.
Scorpion EXO Covert
The Covert is a half helmet with a modular twist: it ships with a removable face mask and sun shield that convert it into a pseudo-three-quarter helmet when you want more coverage. The face mask is not rated for impact protection — it is a wind, sun, and debris shield — but it extends the utility of a half helmet for riders who want the open-air experience in warm conditions and some face coverage in cooler weather. Without the mask, it is a clean, low-profile half shell with DOT certification and a subtle aesthetic that sits flatter on the head than most half helmets. The fit runs slightly small; size up if you are between sizes.
HJC IS-Cruiser
HJC builds the IS-Cruiser for the cruiser and bagger crowd that wants a clean half helmet without paying premium prices. The polycarbonate shell comes in multiple sizes (not a one-shell-fits-most approach), which means the medium actually fits like a medium rather than a small shell with more padding. A retractable internal sun visor provides shade without the snap-on visor look. The SilverCool interior liner is antimicrobial and moisture-wicking. At this price, the IS-Cruiser is the best value in the DOT-certified half helmet category. The retention is a micro-buckle chin strap — quick to operate with gloves.
Daytona Skull Cap
The Daytona Skull Cap is the no-frills entry point. It is a simple DOT-certified half shell with a D-ring chin strap, a snap-on sun visor, and a minimal interior. There is no internal sun shade, no removable liner, and no speed-dial adjustment. What there is: a genuine DOT-certified EPS liner in a shell that costs less than a tank of gas on most motorcycles. For riders who want legal head protection at the absolute lowest cost, the Daytona delivers certification without extras. Expect the interior to wear faster than premium alternatives, and budget for riding glasses since the snap-on visor provides minimal eye protection.
Eye Protection Is Your Problem
Half helmets do not include face shields. Eye protection is entirely on the rider. State laws vary — many states that do not require helmets still require eye protection. Options include riding glasses (which wrap around the temples and sit snug to prevent wind from entering around the lenses), MX-style goggles (more coverage but less common with cruiser aesthetics), and snap-on visors that attach to the helmet's three-snap brow. Snap-on visors provide shade but minimal wind protection — they are open at the sides and bottom.
If you ride a half helmet regularly, invest in dedicated riding glasses with interchangeable lenses — clear for night, tinted for day, yellow for dawn and dusk. Standard sunglasses allow wind to enter from the sides and top, which causes tearing and reduces visibility at speed. Purpose-built riding glasses use gaskets or close-fitting frames that seal against the skin and block peripheral wind without creating pressure points during a long ride.
Retention and Fit
Half helmets rely heavily on the chin strap for retention because the helmet itself does not wrap around the head far enough to stay in place through friction alone. A half helmet that fits loosely can rotate backward off the head in a crash — leaving the forehead and face exposed just when impact occurs. The chin strap must be snug, and the helmet should sit level on the head without rocking forward or backward when you push on the peak.
D-ring straps are the most secure retention system available and are standard on many half helmets. Micro-ratchet buckles are faster to operate, especially with gloves, and provide acceptable security. Snap-button chin straps — common on the cheapest half helmets and novelty items — are the least secure option and are not recommended. They can unsnap under impact forces that D-ring or ratchet systems would hold through.
Size matters more in half helmets than in full-face helmets because there is less helmet to distribute the holding force. A half helmet that is even one size too large will move on impact. Measure your head circumference carefully, consult the manufacturer's size chart (they vary between brands), and if you are between sizes, choose the smaller option. The interior padding will compress slightly with break-in and settle into a custom fit within the first few rides.
When a Half Helmet Makes Sense
Half helmets occupy a specific niche: low-speed riding in warm conditions where the rider prioritizes airflow, peripheral vision, and a minimal equipment footprint. Urban scooter commuting at city speeds, cruiser boulevard rides, and short-distance errands in hot weather are the practical use cases where half helmets are most commonly worn and where their ventilation advantage over sealed helmets is most noticeable.
For sustained highway riding, touring, sport riding, or any riding where crash speeds are likely to exceed 30 mph, a full-face or three-quarter helmet provides meaningfully more protection — specifically to the chin, jaw, and face, which are the areas most likely to contact the ground in a crash and which a half helmet does not cover at all. The choice is the rider's to make, and making it informed is the purpose of this guide.
Frequently Asked Questions
Are half helmets safe?
DOT-certified half helmets protect the crown and upper skull to the same impact standard as full-face helmets — for the areas they cover. The face, chin, jaw, and lower skull are left exposed. A DOT half helmet is safer than no helmet, but provides substantially less total protection than a full-face or three-quarter design.
How can I tell if a half helmet is really DOT certified?
Check for the DOT sticker on the exterior rear, and verify that the liner has at least three-quarters of an inch of EPS foam. Novelty helmets are sold widely and look similar but lack certification and meaningful impact absorption. If a half helmet feels unusually thin and light, it is almost certainly a novelty item.
What is a three-quarter helmet vs a half helmet?
A three-quarter helmet covers the skull, forehead, temples, and ears, extending down to the jawline without a chin bar. A half helmet covers only the crown and upper skull, ending above the ears. Three-quarter helmets provide more coverage and can accept face shields.
Do half helmets have visors?
Most include a snap-on sun visor for shade, and some have a retractable internal sun shade. None include a full face shield — the shell does not extend far enough forward. Riding glasses, goggles, or a snap-on shield are the options for eye protection.
