Evans Real Feel RF6D 6" 2-sided Speed and Workout Pad
The Real Feel pad is probably the most popular practice pad because it does a great job of warming your hands up quickly. The RF6D features a soft side and a hard side with the soft side being a bit softer than an actual drum and great for building strength. I usually use the soft side for pre-gig warmups because it is quiet and can even be played on stage. The hard side is great for practicing rolls, because it makes me work hard to get my own rebound. There are larger sizes available, but I like this 6 inch model because of the small size so you can even fit it into a stick bag if needed.
