The softness of this yarn is heavenly it definitely feels better than what you'd imagine of superwash. Even better, in my opinion, are the variety of exquisit colours! I used Pearl Ten for my last project and in some lights it looks blue-ish purple, in other lights it looks black and it often looks gray... perfect colourway for my boyfriend who's pretty conservative in the colours he likes to wear.
The only downside that I've discovered thus far is that there's a slight pilling and fuzzing effect. I've read that the softer the yarn, the more quickly it'll pill so I guess that's just part & package of having such a squishy, soft yarn. I'd use it more for items that don't see a lot of friction like hats & scarves or where you mightn't mind some fuzzing or pilling like mittens rather than something like a sweater.
