Size
Sizes in which this helmet model is available.
A suitable size is determined primarily by the circumference of the head — its coverage at its widest point, at the level of a couple of centimeters above the eyebrows. Sizes are indicated everywhere as standard —
XXS,
XS,
S,
M,
L,
XL,
XXL, etc. — however, these designations may correspond to different actual helmet sizes for different manufacturers. For example, size S for one brand may be designed for a head circumference of 56 cm, for another — for 52 – 54 cm. In addition, men's and women's helmets (see "Type") of the same size may also differ. Therefore, to select a helmet that is suitable for head coverage, it is best to use special tables that take into account the points described above.
Also note that helmets of the same size can differ markedly in internal shape and other features. Therefore, when choosing, you need to take into account not only the size, but also the actual convenience — the helmet should sit tightly on the head, but not compress it.
Detachable lining
The presence
of a removable lining in the design of the helmet.
The removable lining practically does not affect the functionality and protective properties of the helmet — except that it is considered poorly suitable for "extreme" professional models, because. does not provide the necessary high level of protection. At the same time, this feature greatly facilitates the care of equipment: the removable lining can be washed periodically in a conventional washing machine, and it is much easier to wash / clean it by hand than a non-removable one.
Detachable ear pads
The presence
of removable ear cushions in the design of the helmet.
This feature is found mainly in helmets for "snowboarding" purposes. When riding a snowboard, good visibility and audibility are important; therefore, the shell of such helmets (unlike classic ski helmets) does not cover the ears, and the role of ear protection is played by pillows, which are actually a continuation of the balaclava. Actually, these pillows can be made removable — for example, for skiing in relatively warm weather, or in case you need to hear as well as possible and keep your ears completely open.
Note that soft pillows protect the ears primarily from the cold; the degree of impact protection for helmets of this design is noticeably lower than in models with a solid shell, covering including athlete's ears. Therefore, helmets with this feature are recommended either for simple riding conditions, or for those cases where good hearing is fundamentally more important than an increased degree of protection.
