Unverified极致轻量和小收纳体积是以耐用性为代价的，面料较薄，在碎石地面或荆棘环境下被刺穿的风险高于厚款垫子82% similarUnverified面料越厚重耐磨（如1000D尼龙）越抗荆棘刮擦但透气差、闷热；轻量款（如20D-40D）透气排湿好但抗刺穿能力弱，密林钻行易破79% similarUnverified去污块密度越高（越硬实、单位体积重）越耐用、越不易掉渣碎裂，选购时优选压缩密度高、手感硬挺的产品；蓬松柔软的低密度块用两三下就磨没了79% similarUnverified面料选耐磨优先看denier（D数），登山碎石路段选600D以上尼龙底部+上部210D轻量透气分区设计，纯薄款在灌木区易被划破74% similarUnverified目数越高（颗粒越细）磨削效率越低但表面越光滑：600目以上属于精抛范畴，一次磨大量材料时高目数纯属浪费工时74% similar
