I wear the 'casualwear' leggings and I think that the children's leggings are made of the same stuff which is lovely and soft without being too ... furry? Sprog has some of the lounge pants which I think are made of pretty much the same stuff (not 100% on that) but I've not tried them as I think I'd be too tall.

But yes, I love the patterns! I have a worrying number of pairs of the leggings and just them and a plain top and I'm set for pretty much anything!
