I'm not sure if they've changed them in the last few years but I've owned a pair for a few years and like them. Mine are really stretchy and super light weight. They are the thinnest pants I own. Good for hot weather, not so much in cooler temps.
I have mixed experiences, and generally run warm/sweat easily. Compare that with your own context.
They are very light, perfectly stretchy, and breathe *reasonably* well.
They ARE soft shell material, and I find they do not breathe well enough for high exertion activities over about 60*.
Additionally, because of how thin they are, you need to be careful/aware when it’s cold. With a silk-weight base layer I am comfortable with easy Nordic skiing down to about 10 degrees, and with grid fleece or mid-weight wool down to about zero- and much colder if I increase activity intensity.
All that to say, they’re a great cold weather active layer, good for temperate conditions, but for hot weather I like the zip-off version, and if I were king for a day I’d add thigh zips a la stone glacier de-havilland.
They also wear very nicely with street clothes, so I appreciate the versitility.
