The Roadcrafter comes in a 2 piece, and IMO is easier to put on. The Darien would be better for hardcore tourning in nasty condition.
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.
