The Pantastar uses the patented TreviXpand device that holds the waistband in three points, and is able to adjust the roundness of the waistband according to the style of the trousers. For example, use a rounder shape for suit trousers, and a flat shape for jeans.
Use the roundness adjustment in combination witht the pleat paddles to obtain the best finishing result, regardless of style and size.
Watch the video of the TreviXpand system to see how it works.
