OK, you've totally clarified it for me. I was originally under the impression that the Roadcrafter was simply the one-piece version while the Darien was the two-piece version of the same garment. I now understand that they're two totally separate styles of protective clothing with the Roadcrafter available in either format. The Darien is only available as a two-piece suit.
I've often remarked that I wouldn't be disappointed with anything coming from that company. All their gear is absolutely top-notch quality.

I've bought a number of their clothing items. Somethings give you what they promise, but few deliver more... all their stuff has. Once I was looking for padding material for some electronics shipping cases, I e-mailed them regarding the visco-elastomer they put in the suits, Andy Goldfine, the President responded to mer personally within the hour. Their heated vests and grip wraps are superb.
