Sergio's mitts are the best that I've ever used, and I have used a LOT of focus mitts. Unfortunately, they are difficult to come by! I'm trying to get a new pair right now myself. Topboxer also makes an excellent focus mitt. From his pictures, it looks like he makes a wide variety of styles. I've only tried one but they are amazing! Other brands that I like are Boon, Ring 2 Cage, and Ultra Fight Gear. I have had 3 pairs of Ultra mitts over the years and they are RIGHT up there with Sergio's.
