MACNA does a very poor job of promoting their stuff. I have seen loads of folk with their gear on though. The prices are not high end. And from what I gather they are properly waterproof. It rains a lot in Holland.
Yesterday I thought I'd found an absolute bargain (66% off list of the all over reflective) - but only in size "S". Had it been in larger sizes I'd have had one - removed the protectors and worn it over my Leathers.
This is a funny idea for motorcycle lighting, but unfortunately the rider can no longer see the road...makes a better road side caution and hazard vehicle.
