I love my Pace weights and use them all the time! Great investment! I also have a pair of 1 pound Nike wrist weight wraps that I use all the time, too!I have a pair of the gloves. Mine don't cover the palm either. Regardless, I found them to really be tough to switch out fast enough. Taking out the sandbag is fast, but putting it back in is another story.
I have since invested in Pace weights. They are magnets in half pound increments. They are super fast to switch out. No need to pause the tape while you fumble around.
