The big drawback for me is that they are quite uncomfortable to wear. They have caused some reamed point with me. In particular, between the fingers. This is probably because that the parts are not made of cotton but an art Faster are. One notices the same if you fancy a tightly pulls the material and therefore on the skin drives how warm is. That's not so blatant in my cotton bandages far.
In addition, the fleece side of the Velcro 5 applications is pretty hairy after vll.. I guess that makes it not long.
