My review of the Roadgear Cheetah gloves over at webBikeWorld.com. Probably my favorite glove since the the Joe Rocket Highside gloves.
Like many sport and race style gloves, the Cheetah gloves are constructed from multiple panels and layers of material. Cowhide leather is used throughout the gloves and was soft right out of the package.
The leather thickness is not specified but they seem to strike a nice balance between durability and flexibility, while the overall suppleness of the leather makes them seem thinner than they are.
