Exactly, designed for sitting on a quad in horrible weather counting sheep. People have been misunderstanding this since day one with Ridgeline.
I couldn't have put it in a better way!
As for the lack of 'features' like vents, pockets etc, I have three points on that. First, at least when I got mine, they were much cheaper than what one sees usually from other companies which are feature-loaded. As I started sewing my own stuff, I realised why; the amount of work involved in vents, pockets, absolutely immense, and usually doubles the time it takes you to make the jacket, more so when it involves stitches that pass the outside layers and need to be taped. The second point is that there are far fewer weak points, bits to break, and leak paths. And third, lots of features add considerably to the weight. Want lots more storage? Get a bag... I know the 'if it's not on you, it's not going with you', but I think there is a lot of pointless hype with pockets these days.
For stalking in potentially horrible weather in remote areas of Scotland, I still opt for these, and just keep them off if not strictly needed. Reliable, lightweight for what they do, rugged, waterproof, silent, and cheap enough to not worry too much if I put a repair on them. My second best choice is old german army flektarns, but I find them noisy and likewise lacking ventilation.
So, for a new acquisition, for static / low intensity, I would highly recommend Ridgeline.
