The collection focuses on Serapian’s signature leathers, including Cachemire leather, textured nappa, and the brand’s Mosaic leather on select larger styles. These materials aim for a balance between softness and structure, so bags keep their shape but still feel easy to wear. Product pages specify the exact leather used for each piece. If you’re choosing between textures, think about whether you prefer a smoother surface or something more tactile for daily use.
