I had never heard of them. On a Google search I only turned up one place in the US that carries them and not a lot of information there.
I also found a lot of people asking about them.
One post elsewhere suggested that they are the old "Dingo" brand that used to be sold here some while ago. If so I have seen one of their bite suites, an old well well abused one. Considering its age it must have been really good when new as it was still in use, though it looked like it had "been through the wars".
