2. 安全情報
Your Smith Holt Helmet is engineered with advanced materials to protect your head during impacts.

Always ensure the helmet is properly fitted and free from damage before each use.
- 適切なフィット: A helmet that is too loose or too tight may not provide adequate protection. Refer to the fitting instructions below.
- 検査： Regularly inspect your helmet for any signs of cracks, dents, or wear to the shell, liner, or straps. If any damage is found, the helmet should be replaced immediately.
- 影響: Even if there are no visible signs of damage, a helmet that has sustained a significant impact should be replaced, as its protective capabilities may be compromised.

3. フィッティングと調整
Achieving a correct fit is essential for the helmet's effectiveness. Follow these steps to ensure your Smith Holt Helmet fits securely and comfortably:
- 頭囲を測ります: Use a flexible tape measure to find the circumference of your head, just above your eyebrows and ears. Compare this measurement to the sizing chart below to select the appropriate helmet size.
- ヘルメットの位置: Place the helmet squarely on your head so that the front edge sits just above your eyebrows. It should not tilt back or forward.
- Adjust Chin Strap: Fasten the chin strap buckle. Adjust the straps so they form a 'V' shape under your ears. The strap should be snug but comfortable, allowing only one or two fingers to fit between your chin and the strap. The chin strap features a soft velvet piece to prevent rubbing or irritation in cold weather.
- 動きを確認する: With the chin strap fastened, try to move the helmet from side to side and front to back. The skin on your forehead should move with the helmet, indicating a secure fit. The helmet should not slide independently.
