The Story Behind ZISI. We knew we wanted to build something of our own — and there was a gap we kept noticing. We loved the aesthetic of minimalist slings, but the designs and build quality we wanted simply didn’t exist locally. Outsourcing wasn’t the answer; the factory samples never matched our vision. So we decided to make them ourselves — from scratch, in the truest sense. We researched fabrics, bought our own machine, and learned to sew from the ground up. Piece by piece, ZISI became something we built with our own hands.
