Practicing with the Intech golf impact bag for just 15 minutes a day can help you develop better Rhythm, technique, endurance, consistency and distance, while encouraging muscle memory and a flat left wrist (for a RH golfer) at impact for on-target shots. This can be used to help winterize your game in the off-season or during the season it can provide same quality practice time at home as hitting countless balls at the range. Easy set-up: fill with towels, clothes, sheets or any cloth-type material through the zippered opening, zip it up and you are ready to practice. Use at home or out on the range and it is safe to use for your golf clubs. Product dimensions: 15" diameter x 10" high.
