The object for the investigation is chemical protective clothing (CPC), which totally coves dressed human body together with gear: breathing apparatus, breathing mask and helmet. The end users of such clothing are the members of rescue team –firefighters.The results of 3D scanning with stationary Vitus Smart XXL scanner and portable Artec Eva scanner are presented. The possibilities to exportscanned bodies into specialized CAD systems for suit design development are analysed. The necessity to understand and to implement corresponding clothing material properties during 3D visualization of garment on CAD systems are presented. Obtained results showed, that virtual fitting supplemented by scanning procedure significantly contribute for the implementation ofmass customization concept not only for traditional garments, but for specializedwork wear, as well.
