The FINIS DRAG-FLY is a resistance training tool perfect for improving swimming performance. - Brand: FINIS - Model Name: DRAG-FLY - Material: Synthetic material - Color: Yellow/Black - Accessories: Rope, buoy Purchased new and assembled, but never used. I bought this thinking it was a variable parachute with a buoy, but I ended up buying something else, so it's just been sitting in my closet, and I'm putting it up for sale. The cord and buoy are made of the same materials used in marine applications, so it seems like it could be used in the ocean. In a pool, it's unlikely to break unless it's used extensively. The mesh bag, instruction manual, belt, covered rope cord with buoy, and parachute are all included. Trendy resistance training. You can adjust the load, so I hope you'll consider it for your training next season. Swimming, competitive swimming
