GX3 is a brand out of Japan that has caught my eye. they have some cuts that I really love. However the down side is the sizing chart:
S size 26.5-29.5 cm
M size 28-31 cm
L size 29.5-32.5 cm
XL size 31-34 cm
XXL size 33-36 cm
What is considered a medium in the US is is an XL I believe that the listings should be inches and not cm.
