SG Training Fit: a back-support belt and an apparel collection, each carrying its own design editor — text, images and finishes rendered live

The belt looks simple but carries real retail complexity. Sizing runs on two separate charts by color and compression: colored belts at medium compression, including a kids size, and off-white belts at light compression a full size larger, in adult sizes. A belt can be bought plain or personalized with names, colors and a logo. Orders run from a single custom piece to wholesale batches for a whole studio, and the belt itself is manufactured in Latvia and finished in the USA.

Both customizers are plain JavaScript written for this store's product pages, over one Ecwid cart. The belt editor renders the design live over a photo of the belt in any of its ten colors: text laid along the belt in any of 44 self-hosted fonts, 14 matte and 12 glitter lettering colors, an uploaded image, and every element dragged, resized and rotated inside the belt's print area. Selecting a color in the editor selects the same option in the Ecwid product form, so preview and order stay in step. The apparel editor goes further: front and back sides with a print area each, layered text and images, 36 lettering finishes across matte, glitter, shiny and pearlflex, multi-line type, and a design-review screen that checks both sides before anything reaches the bag. On checkout the editor flattens each side into a PNG and files it into the order's native upload fields programmatically, next to the shopper's own artwork; every design is also saved through a backend API. The editors sit inside a hand-coded eight-page storefront; any item can be bought as-is, and wholesale runs are quoted by email.
