This no-slap padded hammer sleeve rests between your leg and your bag. It fits most hammers as designed and is sewn directly onto your bag, making it stationary and easier to slide your hammer into. Although this hammer sleeve will work just fine with rubber handled hammers, there may be a short break in period. If you swing wood, it should slide in smoothly from the get-go. This item needs to be ordered with the bag on which you'd like it mounted. There is currently no retrofit option.
