I wore these to work because my hands are cold when I get to work.  I ordered the brown and am wearing them now at work as I type this review.  These warmers kept my hands warm all day and there were times that I just had to take them off because my hands got a little too warm.  They are nice quality handwarmers.  I was very skeptical about these from reading others reviews about the buttons falling off.  But this weekend I am going to take the time and reinforce the buttons by threading them again about two or three times with some brown thread and I am done.  These are not gloves!!!  But you can put your gloves on first and then put these over your cloves for added warmth. My co-workers want them now and asking where I got these as it is cold in our office when we get in.  I will be ordering more and some later for Xmas gifts for my co-workers.

Thanks for a wonderful and warm product!!!!
