Not familiar with superwash in general (except Madelinetosh). This is fairly soft, with remarkable stitch definition--super sharp. Crisp (feels a bit like cotton) with a slight tendency to split. The color is not so rich or deep, but perhaps this is a superwash property (except for the exceptional Mtosh). Would buy again for definition and gifts for guys who wouldn't even think of hand washing.
I ended up choosing this yarn as I was knitting Harry Potter scarves for my kids, so the yarn had to be long-lasting, machine washable, soft next to the skin AND come in some pretty damn specific colours! It also needed to be high quality and easy to work with as I'm not a particularly good knitter and need all the help I can get. The yarn ticked all boxes. The scarves finished beautifully and my kids wrap themselves up and say "Mmmm, cosy!" I plan to use it again for a Fair Isle hoodie for my daughter.
Once again I have very pleased with the service price and product I recieved from JB. Amidst the Christmas rush, I realized I was short a skein for a blanket I was making for my grandaughter.
Not only was it in stock, you shipped it to me in time to finish it for Christmas!
You are my go to company and I am happy to tell all my knitting friends to give you a try.
Happy New Year!
