Great for going shopping in on wet days. The fabric is Epic, which means the fibres are encapsulated in silicone. You should be able to reactivate them, if tired, by tumble-drying or ironing. Not waterproof, as pointed out, very wind resistant, shower resistant, don't absorb as much water as untreated denim and then dry faster.
The slimmer cut, ,ime, is hopeless unless you're very skinny. Aesthetically, not bad, but not quite right either, if that makes sense. Feel quite like untreated denim, but you can feel a slight slipperiness to the fabric, though the protos were less obviously so.
I wouldn't wear them for riding personally, looser ones okay for bouldering on dry to occasional drizzle sort of days, breathability is decent, far better than Gore-Tex.
