10 Best Cycling Helmets 2025 in the United States

The Schwinn Thrasher Bike Helmet is designed for adults aged 14 and above, with a suggested fit for head circumferences between 58-62cm. One of its key strengths is the customizable fit provided by the adjustable dial system and adjustable side straps, ensuring comfort and security. The helmet is lightweight due to its two microshell layers and full-coverage EPS foam construction, making it easy to wear during long rides. With 21 flow vents, it offers excellent ventilation, helping to keep the rider cool even during intense cycling sessions.

The detachable visor is a useful feature that provides shade and reduces glare, enhancing visibility in sunlight. It also complies with U.S. CPSC Safety Standards, which is a crucial aspect for safety-conscious users. However, it lacks MIPS technology, which is beneficial for additional brain protection against rotational forces during impacts. Additionally, it does not have a light option, which could be a drawback for riders who cycle in low-light conditions or at night. The moisture-wicking pads contribute to comfort by keeping the rider dry. The Schwinn Thrasher helmet is a solid choice for those seeking a comfortable, well-ventilated, and safe cycling helmet, though it might not be ideal for users requiring MIPS technology or built-in lighting for enhanced visibility.

The Giro Fixture II MIPS Mountain Bike Helmet is designed for universal adult use, fitting head sizes from 54 to 61 cm. Its standout feature is the integrated Multi-Directional Impact Protection System (MIPS), enhancing safety by redirecting energy during crashes. This helmet is notable for its market-leading protection, tested in Giro's own lab, and its rugged in-molding construction for durability. Ventilation is excellent with 18 Wind Tunnel vents, ensuring good airflow during rides to keep the rider cool.

At just 10 ounces, the helmet is lightweight, which adds to the comfort for longer rides. The adjustable fit system allows for a quick and comfortable fit right out of the box, accommodating a wide range of head sizes and shapes. The Matte Titanium color is sleek and appeals to a broad audience. Additionally, the helmet receives high marks for comfort, thanks to its foam inner material and a universal fit that suits various users, including men, women, and kids.

However, it may lack advanced features for serious mountain bikers, like a visor for sun protection or advanced adjustability options found in higher-end models. Visibility features aren't specifically highlighted, which could be a consideration for night riders. It's a well-rounded helmet, particularly suitable for recreational cyclists and those seeking reliable protection at a reasonable price point.
