Big size glove brands?
 

Can anyone recommend a brand name that makes cycling gloves beyond size 11 (XXL)?

Giro and Pearl Izumi both make some of their styles up to 3X. I can get away with 2X in many if they're fingerless, but in full finger not so much-- fingers like a spider I've got. Aerotech designs makes some really big gloves, pretty much the only full-finger gloves I can wear.

If you've got what I call "bear paws," which is big palms with not-so-long fingers, your selection is going to be severely limited. Sadly. Not that my selection is worlds better.
