Raw-cut at every edge - neckline, armholes, hem - and the density of the Italian jersey holds each one clean without a single stitch of reinforcement. The fabric is a fine-gauge Italian stretch jersey - smooth, tightly woven, dense enough to hold its shape flat against the body without pulling. The neckline, armholes, and hem are cut raw. No binding, no topstitch, no ribbed trim. The jersey's own density holds the edges clean. The silhouette is elongated so the tank can sit tucked into a waistband without pulling short when you move. Fit is close but quiet - second-skin in the engineering sense, where the fabric absorbs the shape of the body rather than compressing it. In direct light the surface carries a very soft sheen from the polyamide content, then reads back to flat black from any other angle. The purpose is a base layer - something built to sit under the rest of the wardrobe without pulling focus, cut with the same attention SAPIO brings to their outerwear.
