As a nurse in home care, I've worn a lot of gloves and must say that they are the best I've ever used. The only of 10 different brands of gloves that are never broken. They are comfortable to wear, have a smooth surface, that is, rub with personal hygiene not mean they are absolutely stable and impervious, theoretically, you could wear them one more time, but not recommended for hygiene reasons. They survive even hitch a wash cycle in the washing machine when you mitwäscht accidentally. Highly recommended. Allergy I have no get, you do not sweat as much as in other gloves.
