They do some funky designs but if you're going for the plain styles why not go for Rapha? If you get the Rapha stuff in the sale I'd suggest with the free lifetime repair service they'll work out better value. https://www.rapha.cc/us/en_US/repair-service
A friend of mine uses Stolen Goat clothing, he has a pair of shorts and a pair of longs along with a couple of tops. Quality is very good, on a par with Rapha or Assos. He recently did a 100 mile ride in the shorts with no issues.
I’ll be honest, my Stolen Goat Orkaan long sleeve is the most disappointing piece of cycling clothing I own, by quite a margin.
The temperature range between "too cold to wear it because it lets too much wind through" and "too hot to wear it because it’s well insulated" is about 0.5 degrees. And the "showerproof"/"water resistant" features are non-existent; it’s capable of going from dry to wetted-through in about 60 seconds of light rain.
I get much, much better value (and pleasure) wearing Castilli when it is (or might be) wet/cold, and Torm for the other 75% of the time.
