Correct Ali Usman.
I know at least 5 women in our circle of friends who wear niqaab. They all go out and do their groceries, pick up kids from school, shop at malls, etc etc etc...they are very comfortable and happy. I think it's the rest of us who have a bigger issue worrying about them, perhaps because we don't feel comfortable in doing that.
Most of the women don't feel comfortable with the veil, while doing their routine work ,esp. in hot countries. But they do so because of religious obligation and that's why say, that they are comfortable with it.But in actual it is not so easy in the summers to go out of your home with the veil.
