The fast-drying Cool-Max model provides the superior, patented metal support of all Robby's Originals, with the added assurance of dryness and comfort that can offer a competitive edge. The Cool-Max Plus combines the benefits of the Robby's Cool-Max with the longer, firmer design of the Robby's Plus.
I bought this to get more wrist support. Twenty years ago, I had the original Robby's leather version, with was very stiff. This material is very comfortable and definitely more flexible. The metal bar "munches" my wrist-bone, however and I can't use it very long. I will be purchasing one of those cotton wrist "sock" liners to wear under it in the hopes it will soften the pressure on the bone. (I'm bony anyway, so this may not be an issue for some people).
