Revgear 41426 Speed Bag Bladder

Personally, I prefer using latex bladders over the plastics. They have a softer response which makes it necessary to hit harder in order to get your speed up. Harder hits = more work = stronger arms and shoulders. The last time I looked, that was pretty much the point of working out. These bladders are also a breeze to install. No adhesive needed and the nipple for the inflator has a nice shoulder to hold it in place. It took me less than 10 minuets from the time I took the bag down to having it back up and ready to go. I buy these 2 at a time so when I wear one out I can get back in action right away. Rev Gear has a great price on these excellent bladders and shipping was quick. Highly recommended.
