I would never had imagined that people with smaller hands would have problems in Thailand, but comparing my hands with two of my Thai co-workers I found out that the size of the hands are not that different.
You can try Dirt Shop in Bangkok, I believe that they sell Alpinestars gloves... but I'm not actually sure if they will stock smaller than regular sizes – probably your problem could be even be bigger then shopping for big sizes.
Anyway if the Thai dealers not have the correct size or the right style of motorcycle gloves you can always look at Motorcycle Gloves.
Decent gloves are quite hard for me to find because of two small problems I have: my hands. They are tiny. Friends even call me a midget... Anyway, Alpinestars has some motorcycle gloves that come in extra tiny sizes for disadvantaged micro-hands types like me so these have got off to a better start then most. Does anybody knows who sells Alpinestars motorcycle gloves in Thailand?
