It would probably be best to try some on to check the size before you buy a box of them.

And they don't last forever. I just put on a new pair today. On one hand, the fingers were fine, but the "cuff" ended up by my elbow. Pity about all that bare skin between... <img src="/images/graemlins/smile.gif" alt="" />

I don't know if they shrink in heat (I don't know why they would), but maybe your hands could swell?
