Wool soakers are pull-on diaper covers. I know it's confusing because the word "soaker" is also used to mean an absorbent cotton or hemp pad in a diaper. Wool soakers are not scratchy or hot. They are actually soft and cool. (I find that the hand-knit merino soakers are much softer than wool fabric wraps. Some wool fabric wraps actually feel a little scratchy to me, but I have SUPER sensitive skin. Anyway, the hand-knit merino soakers are like BUTTER. *Nothing* scratchy about them. They bear no resemblence to the scratchy wool in the sweaters that you have experinece with.) I love wool because it's natural and breathable and easy to care for. It's the only natural fiber diaper cover. Also, I find that wool soakers work better than diaper covers made out of any other material. They are ideal for containing any fluid that might escape from the diaper. They can catch 30% of their weight in liquid without feeling damp on the outside. Give wool a try and I bet you'll fall in love.
