Comparison LS2 FF396 FT2 vs LS2 FF323 Arrow R

A type of fastener used on a motorcycle helmet to secure a chinstrap.

— D-Rings. A classic clasp that is still popular today due to its combination of simplicity and reliability. The basis of the design is a pair of D-shaped rings (hence the name). When properly applied, these rings firmly clamp the belt passed through them, and the free end of the belt is fixed to the clasp-button or magnet. In addition to a secure hold, the advantages of D-Rings include the fact that size adjustment is made on the fly every time, directly when fastening; this is especially convenient for a "passenger" helmet, which has to be used by different people. On the other hand, the fastening-unfastening process itself is not very convenient: it requires a certain habit and takes more time than in other fasteners.

— Quick click. The classic Quick-Click design resembles a car seat belt buckle: on one half there is a metal plate with a hole, on the other there is a lock that automatically fixes this plate and opens at the touch of a button. It is believed that such fasteners are less reliable than D-Rings, however, with proper workmanship, this difference is not significant; and fasten and unfasten Quick-Click much faster and more convenient. Also in this category are "fastex" — fasteners, familiar to many from tourist equipment. "Fastex" has the form of a trident, fixed in a special nest, such a lock opens by...pressing from the sides; this variety has not received much distribution, as it is considered not very reliable.

— Ratchet. Also known as Quick-Release. One half of such a clasp looks like a strap (usually plastic) with a special notch, a lock is installed on the second. The strap can move through the closed lock only in one direction — to tighten, this is how the “ratchet” fastens (with a characteristic sound, hence the name). To unfasten it, you need to open the lock, giving the strap the opportunity to move in the opposite direction. This design allows you to quickly and easily remove and put on the helmet, while, like the D-Rings, it automatically adjusts to size with each fastening. At the same time, fasteners are considered not very reliable, but in fact it all depends on the quality of workmanship (which, usually, is directly related to the price category of the helmet).

The type of visor used in the helmet. In this case, a visor means glass that covers the motorcyclist’s face from wind, dust, raindrops, etc., and often also from the bright sun. Note that there is a specific category of visors - sun protection; they are not taken into account in this case; for more information about such devices, see “Functions/capabilities”. Traditional visors can be like this:

- Transparent. Classic transparent glass that does not change the visible image. In bright sunshine, such visors are less comfortable than tinted ones, but this disadvantage can be compensated for by using additional sun visors (see below). At the same time, transparent glasses do not impair visibility in the twilight and are generally more versatile, and therefore are used in most helmets that generally have visors.

— Tinted. Visors with tinting. As a rule, we are talking about a certain degree of shading - from light “smoky” to almost black or mirror (glasses tinted yellow or orange have their own specifics, so they are indicated separately - see below). The darkened visor improves visibility in bright sunshine; in addition, it is often made polarized, which also reduces the amount of visible glare (from water, from shiny metal surfaces, etc.). On the other hand, through such glass it is worse to see in the evening and at night than through transparent glass - up to the complete impossibili...ty of using a helmet with a closed “visor” normally. So tinted visors are recommended for daytime driving only.

— Tinted/transparent. This option is indicated for models available in different configuration options - both with a tinted and with a transparent visor. This allows you to choose the option at your discretion, depending on personal preferences and expected driving characteristics. And some models can be equipped with both types of glass, which makes the helmet universal right out of the box.

- Yellow. Visor tinted yellow or orange. These glasses are the opposite of tinted visors: the yellow color increases image brightness and contrast, improving visibility in low light conditions - from cloudy weather to evening and night driving. But in daylight, even not very bright, the yellow color can cause discomfort (although it all depends on the user’s preferences). In general, this is a rather specific category; it is rarely installed in helmets as standard: it is believed that the need for yellow glass rarely arises, and if it does arise, such a visor can be purchased separately without any problems.

- Absent. By definition, cross-over helmets designed for use with glasses do not have visors; In addition, glass is missing in some open models (see "Type"), in which such equipment does not fit due to construction or design considerations. But in other types of helmets this option practically does not occur: if a given model allows the installation of a visor, it is almost certainly equipped with at least the simplest transparent glass.

— Quick release visor. The ability to quickly remove the helmet visor, in most cases without the use of special tools. Such an opportunity can be useful, for example, for cleaning from pollution, replacing transparent glass with tinted glass, or vice versa.

— Anti-fog coating. The presence on the helmet visor of a special coating that prevents fogging from the breath of a motorcyclist. This feature will be useful especially in cold weather (glasses practically do not sweat at high air temperatures). It is especially important for closed helmets (integral and enduro, see "Type"), but can also be found in open ones. Note that such a coating is not a 100% guarantee against fogging, but the likelihood of this phenomenon is greatly reduced.

— Sun visor. A sunscreen in the form of additional tinted glasses that can be lowered and raised as needed, usually by means of a small lever or button on the side of the helmet. Do not confuse this device with tinted glass (see "Visor" above): a sun visor is provided as an addition to the main visor and covers only the eyes. By lowering and raising such glasses, you can “turn on” and “turn off” additional dimming. At the same time, the main visor is most often made transparent, thanks to which the helmet can be comfortably used at night — just lift the built-in glasses and look through the transparent glass. However,...the sun visor can also be combined with tinted glass; this option will be appreciated by people with sensitive eyes that do not tolerate sunlight well and require enhanced darkening. The disadvantage of this feature is a noticeable increase in the cost of the helmet.

— UV protection. Availability of UV protection in the glass and/or helmet sun visor (see above). Intense ultraviolet light is harmful to the eyes, it leads to their rapid fatigue, deterioration of vision, and sometimes even eye diseases. Moreover, such radiation can be quite intense not only in sunny, but even in cloudy weather; in addition, the amount of ultraviolet increases in mountainous areas as altitude increases. However with short-term exposure, the described effects are hardly noticeable, but even for trips over short distances, UV protection will be useful. And if you are going to travel "far and long" — this feature is highly desirable. Note that if necessary, UV protection can be provided using separate glasses (motorcycle or conventional), but not all helmets allow the use of such glasses.

— Built-in ventilation. The ventilation system usually has the form of holes in the shell — the air flow entering them "blows" the inside of the helmet. This not only provides comfort (especially in hot weather), but also reduces the amount of moisture accumulating inside: the rider's head sweats less than in a fully closed helmet, and the sweat that is released quickly evaporates and is blown into the ventilation. At the same time, many models provide the ability to completely or partially block the ventilation — for example, in cold or rainy weather.

— Breath cutter. Most often found in helmets of a closed design (integrals, modulars, enduro — see "Type"). In such models, it is a kind of visor that covers the nose and mouth of the motorcyclist — so that the exhaled air is discharged into the lower part of the helmet and the visor does not fog up. Also, sometimes cut-offs are called additional masks that are equipped with open helmets, but this is not entirely true — such masks have a slightly different purpose, they are mainly designed to protect the mouth and nose from dust, small litter, insects, etc.

The results shown by this helmet model in the SHARP safety rating.

SHARP is a comprehensive testing methodology designed to determine the degree of protection and safety level when using a helmet. Each helmet is tested for direct (linear) impact as well as glide impact friction; in the first case, the acceleration acting on the motorcyclist's brain is measured, in the second, the twisting force acting on the neck is also measured. Tests are conducted for different points of impact, each test involves a minimum of 32 test collisions (more if necessary). The data obtained is compared with information about real injuries, and based on this, the helmet is rated on a five-point scale — from 1 to 5 stars.

The higher the SHARP rating, the safer the helmet and the lower the chance of serious injury while wearing it. However, when choosing this parameter, it is worth considering some nuances. First, the SHARP check is only done on models sold in the UK; and therefore the absence of such certification does not mean poor protection — it may indicate that the helmet simply did not make it to the test. Secondly, the cost of a helmet practically does not affect the number of stars: neither 5 stars for a low-cost model, nor 2-3 stars for a top one are rare. Thirdly, the SHARP programme only checks safety in collisions, it does not affect issues of convenience, aerodynamics, visibility, etc. And even the SHARP experts themselves recommend choosing the most conveni...ent models first, and only then choosing the option with the highest number of stars.
