When choosing a motorcycle helmet, multiple factors need to be considered comprehensively, including helmet type, material, safety, comfort, breathability, size, and additional functions. Here are some purchasing suggestions and three recommended brands of motorcycle helmets.

Suggestions for purchasing motorcycle helmets
Type selection:
Full helmet: provides the most comprehensive protection, suitable for high-speed cycling and long-distance travel, but with relatively limited visibility and heavy weight.
Three-quarters helmet: covering most of the head, leaving the chin exposed, with good visibility and breathability, suitable for urban cycling and short trips.
Half helmet: the lightest, mainly protecting the top of the head, suitable for summer cycling, but the protective performance is relatively poor.
Material selection:
Carbon fiber: lightweight and strong, but expensive.
Fiberglass: Its strength and weight are between carbon fiber and plastic, making it a cost-effective option.
Plastic (such as ABS): Affordable in price, but heavier in weight and lower in strength.
Security:
Ensure that the helmet complies with national safety certification standards such as DOT, ECE, etc.
Check if the helmet has an internal cushioning layer to reduce the impact force during impact.
Comfort level:
Choose a size that fits your head shape, ensuring that the helmet is tightly attached to the head but not compressed.
Good ventilation system to maintain coolness during cycling.
Additional features:
Consider whether additional features such as sunshade lenses and removable washable lining are needed.
