## Overview
- **Product**: FF396
- **Brand**: N/A
- **Category**: Helmet
- **Summary**: 专为热衷弯道穿梭的骑士和城市通勤者优化设计，LS2 FF396 专为征服密集交通的日常城市导航者打造。其高抗冲击聚碳酸酯/Lexan 外壳重量仅为 1342 克，轻盈如羽，通过边界层气流管理，在满足 ECE 22.06、DOT FMVSS 218 冲击标准的同时，保持约 85 分贝的声学座舱轮廓。内部采用吸湿排汗抗菌衬里，贴合 Intermediate Oval 头型，集成眼镜通道和适合戴手套操作的快拆棘轮扣。 FF396 是 LS2 打造的高结构强度 全盔 安全防护装备，其外壳采用 碳纤维高强度复合盔体 制造。多重复合层叠结构能够在发生撞击时实现阶梯式动能吸附与扩散，有效将冲击载荷分散到外层壳体表面，最大程度减缓冲击能量向内部多重密度 EPS 缓冲层的传导。 通过严苛的 ECE 22.06, DOT FMVSS 218 安全认证标准，该盔体经过严格的直线减速与倾斜角冲击测试，有效削减引发弥漫性轴索损伤的旋转加速度。关于跌落测试初速度与撞击砧板几何规范的深度解读，请查阅我们的工程指南：ECE 22.06 对比 DOT 与 SNELL 头盔安全标准指南。 内衬工效学基于 中椭圆型（Intermediate Oval） 颅骨结构进行三维塑形，消除顶骨边缘的局部压痛点，同时保持颧骨弓部位的均匀贴合压感。如需了解佩戴稳定性与内衬磨合指导，请参考我们的 头型分类与颅骨几何贴合指南 与 脸颊内衬密度与贴合磨合规范。 在时速 100 公里/小时巡航工况下，舱内风噪值实测约为 87 dB，这得益于内嵌 EPS 风道导流与层流外形设计。若需进一步分析不同壳体材质在长期紫外线及热疲劳下的力学耐久表现，请参考我们的 碳纤维、玻璃纤维与聚碳酸酯复合盔体材质对比。 车辆协同效应与骑行场景： ... 阅读更多
