Abstract: A device for training swimmers includes a swimsuit, one or more drag-creating strips, and fastener(s) for detachably fastening the drag-creating strip(s) to the swimsuit. Each drag-creating strip includes non-porous material forming at least one pocket having a closed bottom, closed sides and an open top.
