While this question is dependent on the federation you compete in, for the most part raw powerlifting entails that no supportive suits are allowed to be worn, and the only allowed equipment is a belt, wrist wraps, and knee sleeves. Within some federations they have a “classic raw” divison, which allows the use of knee wraps, but for most people new or just getting into the sport of powerlifting the term “raw powerlifting” usually seems to be associated with the raw classes using knee sleeves, which provide less support. Raw powerlifting has exploded in popularity over the past couple years, most likely due to the fact that the barrier of entry is much lower than equipped powerlifting, and also the fact that is probably is a bit more appealing to those transitioning from bodybuilding training to a strength sport.
