Have you tried on POW gloves before? I've noticed they seem to run a little small so I've had to bump up a size on my POW gloves/mittens over what I'd usually get with a Dakine/Burton/Drop glove.
the gloves arrived today.
they look and feel really good, but like you and others have suggested they do run a bit small.
when I measured my hands I was 21.5cm right between Medium and Large according to the POW sizing guide. I ordered Large... I'm glad I did, because they fit perfectly... Medium would definitely have been too small for me.
i haven't tried them on with liners yet... hopefully they still fit alright
