Abstract: Weighted articles of apparel having an adjustable fit and methods of manufacturing the same. In aspects, upper body, lower body, or full or substantially full body weighted article of apparel having an adjustable fit are provided. Fit-adjusting features or mechanisms can be incorporated into the weighted articles of apparel to allow a fit, tightness, or constriction of a wearable portion and/or the weighted portions to be adjusted, thereby allowing weights to more directly transfer forces onto a wearer in desired areas. The fit-adjusting features can include zipper-mechanisms that can be secured or unsecured while still remaining connected by a connecting textile, e.g., such as a gusset.
