手机保护套常见分类
1、皮套
在各类手机保护套中，皮套也很受欢迎。相对于样式单一的硅胶套，在职场打拼的商务人士更喜欢使用大方体面的皮套，和崇尚休闲的年轻人不同，拿着款外表颜色单一的手机对他们而言是有失大雅的。
2、硅胶套
硅胶套，材质为硅胶，即硅橡胶（silicone rubber）。硅胶套是最为人熟知的手机保护套类型。它质地柔软、手感略滑，流行市场已经多年。从粗制滥造的地摊货发展到做工精良的个性品牌，市场份额始终保持领先。因为其卓越的性价比，硅胶套在后来MP3、iPod火爆的时候，也大行其道，受到许多人的青睐。
3、水晶壳
硅胶套和皮套各有千秋，也各有不足，为实现综合保护，又一种手机保护套应运而生。这就是备受女性青睐的水晶壳。它由有机玻璃制作而成，外观厚实坚固，壳身晶莹剔透。不仅能有效保护手机，而且也不大影响外观，可谓深得硅胶套与皮套之长。
