Re: If you had to pick just one kind of wool...
I used Aristocrats exclusively with my now 18 & 15 yr olds. I don't think there were other wool options then! LOL! Not much chance of them fitting under clothes! I've used Disana & they are a little bit less bulky, but not much. Lana is good,too. They are not the same style, but more likely to fit under clothes.
