Never had the pleasure to meet the man, but Darvin's got to be a cool dude. He has some of the coolest, cleanest gear on the planet, including all those MSA examples.
I've always been impressed with his detail orientation and the design and craftsmanship in the mechanisms and parts he needs too.
David got it wright, a great guy. I met Darvin in 2007 in St. Louis and we spent most of the day in the jazz room. we have since bought and sold gear to each other and I am proud to have met him and visited with him.
