Most bikers wear a helmet, and the type they choose depends on how much protection, airflow, and comfort they want. Helmets range from full-face models that cover everything to minimalist half helmets that barely cover the crown. Beyond the helmet itself, many riders also wear under-helmet liners, balaclavas, and goggles to deal with sweat, cold, wind, and sun.
Full-Face Helmets
A full-face helmet is the most protective option. It wraps around the entire head, including a chin bar and a visor that shields the face from wind, debris, and bugs. The chin and jaw account for a large share of impact zones in motorcycle crashes, so covering them matters. Full-face helmets also tend to be the quietest and most aerodynamic, which makes a real difference on highway rides where wind noise can cause fatigue over a few hours.
The trade-off is heat. A full-face helmet encloses your head completely, so ventilation design becomes critical. Modern versions route air through intake vents on the forehead and chin, pushing it across the top of the head and exhausting it out the back. In stop-and-go city traffic on a hot day, though, even good vents won’t keep you as cool as a more open design.
Modular (Flip-Up) Helmets
Modular helmets look like full-face helmets but have a chin bar that flips up on a hinge. This lets you eat, drink, or talk without removing the whole helmet. They’re popular with adventure and touring riders who want full-face protection on the highway but flexibility at gas stations and rest stops. When the chin bar is locked down, a modular helmet functions similarly to a full-face, keeping dust and dirt out and reducing wind noise. When it’s flipped up, you essentially have an open-face helmet.
The hinge mechanism does add a small amount of weight and introduces a potential weak point compared to a one-piece full-face shell. That said, any modular helmet carrying a safety certification has been tested with the chin bar closed and met impact standards in that configuration.
Open-Face and Half Helmets
Open-face helmets (sometimes called three-quarter helmets) cover the top, back, and sides of the head but leave the face exposed. They give riders a wider field of vision and more airflow, which makes them a favorite among cruiser and scooter riders. Some come with a snap-on visor or face shield, but there’s no chin bar.
Half helmets take minimalism further, covering only the top of the skull. They’re the lightest and least restrictive option, but they also offer the least protection. Both styles produce significant wind noise and leave the chin, jaw, and face completely unguarded. Helmets are 37 percent effective at preventing rider deaths and reduce the risk of head injury by 69 percent, according to the CDC. That protection drops substantially when less of the head is actually covered.
Novelty Helmets vs. Certified Helmets
Some riders wear what look like helmets but are actually novelty items sold without safety certification. These are common in skullcap or German army styles and can be difficult to distinguish from real helmets at a glance. The differences are significant once you know what to look for.
A certified helmet weighs about 3 pounds and contains roughly an inch of firm polystyrene foam that absorbs impact energy. A novelty helmet typically weighs a pound or less and contains only soft foam padding, or no padding at all. Certified helmets also have sturdy chinstraps with solid rivets, while novelty versions often use flimsy straps. Any protrusions like spikes or decorations extending more than two-tenths of an inch from the surface are a red flag, as they violate the DOT safety standard. If the helmet lacks a DOT sticker on the back along with manufacturer labeling (name, model, size, date of manufacture), it almost certainly hasn’t been tested to protect you in a crash.
Safety Certifications to Look For
Every motorcycle helmet sold in the United States must meet the DOT standard (FMVSS No. 218), which tests for impact absorption, penetration resistance, and chinstrap strength. Testing involves dropping a helmeted head form onto anvils and checking whether the force transmitted to the head stays below dangerous thresholds. A separate penetration test drops a six-pound spear-like striker onto the helmet from 10 feet. If it pierces the shell and contacts the head form, the helmet fails.
The ECE standard, used widely in Europe, adds a curbstone-shaped anvil to its impact tests. The newest version, ECE 22.06, also includes flat and angled anvil tests. For riders who race or want the highest level of certification, the FIM’s latest standard (FRHPhe-02) incorporates oblique impact testing and becomes mandatory for competition in 2026. For everyday street riding, a DOT or ECE certification is the baseline you want to see.
Shell Materials and Weight
Helmet shells are made from three main materials, and each handles impacts differently. Polycarbonate (plastic) is the heaviest but also the most affordable. It flexes on impact, which actually makes it effective at spreading energy across the shell during lower-speed crashes. The downside is that you need more material to get adequate protection, so these helmets tend to be bulkier.
Fiberglass sits in the middle. It’s lighter than polycarbonate and still disperses some impact energy across the shell, though not as effectively. It needs a slightly thicker foam liner to compensate for the energy it doesn’t absorb through the shell itself.
Carbon fiber is the lightest and most rigid option, which is why it dominates high-end and racing helmets. That rigidity makes it excellent at handling high-speed impacts, but it performs less well in low-speed knocks where a more flexible material would spread the force better. Carbon fiber helmets also show damage more visibly after any impact, making it easier to know when a helmet needs replacing.
Visors, Shields, and Eye Protection
Full-face and modular helmets come with a built-in visor (also called a face shield) that protects against wind, rain, and UV light. Many helmets now include an internal drop-down sun visor, essentially a tinted lens that slides down behind the main shield at the push of a button. This eliminates the need to swap between clear and tinted visors or wear sunglasses under the helmet.
Some helmets offer photochromic visors that darken automatically in sunlight, similar to transition lenses in eyeglasses. Rider experience with these is mixed. They generally don’t get dark enough to replace proper sunglasses, and the photochromic coating degrades over time. After two to three years of use, many riders report their visor barely darkens at all.
For open-face and half helmets, goggles or riding glasses are the primary eye protection. They seal against wind and debris and come in clear, tinted, or interchangeable lens options.
Under-Helmet Liners and Balaclavas
What you wear between your head and the helmet padding matters more than most new riders realize. A thin skull cap or helmet liner made from moisture-wicking polyester or a polyester-spandex blend pulls sweat away from your scalp and keeps it from soaking into the helmet’s interior padding. This keeps the helmet fresher, extends the life of the liner inside, and reduces the frequency of deep-cleaning your helmet.
Balaclavas cover the entire head and neck, with an opening for the eyes or face. In warm weather, a lightweight balaclava wicks sweat and provides UV protection for the neck and ears. In cold weather, thicker versions made from micro-polar fleece or neoprene add wind resistance and insulation. Some cold-weather face masks cover from the nose down to the chest, blocking wind from reaching the neck and upper torso.
For riders concerned about hair breakage or helmet hair, silk helmet liners are a popular solution. The ultra-thin silk reduces friction between hair and the helmet’s interior, preventing snagging and the kind of repeated pulling that causes breakage over time. They’re thin enough that they don’t change the helmet’s fit.
Smart Helmets and Tech Integration
A growing category of helmets includes built-in technology. Bluetooth communication systems, either factory-integrated or added as aftermarket modules, let riders listen to music, take phone calls, and talk with other riders through mesh intercoms. These typically mount inside the helmet with speakers near the ears and a microphone near the chin.
At the higher end, helmets like the CrossHelmet X1 integrate a heads-up display that projects navigation and speed information onto the visor, a rear-view camera feed, active noise control, and a touch panel for adjusting settings. These features are still niche and expensive, but they represent where helmet design is heading. For most riders, a simple Bluetooth module added to a quality certified helmet covers the practical communication and audio needs without the premium price.
