After more than 4 years the good old Hard Nox I has been replaced. We analysed all our experiences (both good and bad) from last few years with the Hard Nox I and simply wanted to make a better pad. We aimed to create a leg guard with our attention focused on maintaining freedom of movement. The two plastic cups are sewn on one double thickness neoprene layer. This gives better absorption and a more comfortable feel on the user's skin. The Velcro securing the knee is thinner than the others in order to prevent rubbing in the fold on the back of the knee. The dimensions of the Hard Nox II are based on empirical values, so in other words?. with the Hard Nox II, one size fits all.
