I got Teknik stuff before christmas, used it through some real shitty weather. I ride 100 miles to and from work and its never let in a drip. I've got sidi gortex boots and alpinestar gortex gloves, got the lot for less than £400. you could spend 2 to 3 times that on more Trendy brand stuff but hey i'm tight.
I'm cheap,dry and warm so what else could i need.
They may or may not claim it. I dunno. All I know is that I stay dry in my Aerostitch Roadcrafter suit. In the hissing rain for hours (literaly) on end. It works, and that's good enough for me...
