Alpinestars(A星)SM5速滑头盔
全新的SM5头盔是经过五年多深入研究、开发和测试的成果。我们仔细研究了每一个可能的方面，设计出一种安全且经过深思熟虑的头盔，以提供最佳保护和舒适度。这款轻质头盔采用热注入外壳，结合了不同厚度的特殊聚合物混合物，旨在提供冲击防护和轻质的最佳组合，而五密度EPS内衬确保了正确区域的正确密度，以增强冲击吸收。其他关键设计特征包括工程凸起区域和衬垫，以有效减少传递到锁骨的力，以及获得专利的遮阳板释放系统，无论碰撞角度如何，都能以正确的预定力释放遮阳板。
特征：
- 轻质外壳由两种尺寸的技术先进的抗冲击热塑性塑料制成。
- 内表面和外表面的设计可将倾斜冲击的影响降至最低。
- 多密度内衬，确保正确区域的正确密度，以增强冲击吸收。
- 获得专利的遮阳板释放系统可确保遮阳板以正确的预定力释放，无论碰撞角度如何。
- 通过多个进气口和排气口，实现了最大程度的通风和高水平的热交换。
- 遮阳板设计用于将空气导入端口，以增强气流。
- 紧急释放系统和可拆卸的颊垫允许在头盔仍然戴着的情况下安全轻松地移除颊垫。
- 采用Silverplus®处理抗菌织物的可拆卸舒适衬里，具有出色的吸湿性，有效地将汗液从皮肤中排出。
- 不锈钢D形环。
- 尺寸中等的重量为1260g（ECE）/1370g（DOT）。
Alpinestars SM5 Speed Motocross Helmet
The all-new SM5 helmet is the result of more than five years of intensive study, development and testing. We scrutinized every possible aspect to engineer a helmet that is safe and thoughtfully designed to deliver optimal protection and comfort. This lightweight helmet features a thermo-injected shell incorporating a special polymer blend enhanced by varying degrees of thickness that is engineered to deliver the optimal combination of impact protection and light weight, while the five density EPS liner ensures the correct density in the correct area for enhanced impact absorption. Other key design features include an engineered raised area with padding to effectively reduce the forces transmitted to the collarbone and a patented visor release system that ensures the visor is released with the correct pre-determined amount of force, irrespective of the angle of impact.
Features:
- Lightweight outer shell is constructed from a technologically advanced impact resistant thermoplastic in two sizes.
- The inner and outer surfaces are engineered to minimize the effects of oblique impacts.
- Multiple density inner liner to ensure the correct density in the correct area for enhanced impact absorption.
- Patented visor release system ensures the visor is released with the correct predetermined amount of force, irrespective of the angle of impact.
- Maximized ventilation and high levels of heat transfer exchange thanks to multi-air inlets and exhaust ports.
- The visor has been designed to direct air into the ports for enhanced airflow.
- Emergency release system and removable cheek pads permit the safe and easy removal of the cheek pads while the helmet is still on.
- Removable comfort liner with Silverplus® treated anti-bacterial fabrics for excellent moisture wicking, effectively drawing perspiration away from the skin.
- Stainless steel D-rings.
- A size Medium weighs 1260g (ECE)/1370g (DOT).
