## Overview
- **Product**: N120-1 Apex 灰
- **Brand**: N/A
- **Category**: Helmet
- **Summary**: 跨界揭面盔/开放式头盔，配备宽阔视野镜片，并支持 N-Com 系统安装。 N120-1 Apex 灰 是 Nolan 打造的高结构强度 揭面盔 安全防护装备，其外壳采用 多重复合纤维盔体结构与多密度缓冲层 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 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： 兼顾下压力平衡与前额高负压进气，针对运动街车与公路巡航骑行姿态进行了针对性调校。整盔重量约为 1603 克，拥有居中的质量重心分布，显著减轻长时间高速骑行造成的颈椎肌群疲劳。欢迎查阅我们的 摩托车车型工程兼容性目录，获取匹配风挡与坐姿协同建议。
