Fairtex does not usually make these as Vegan but I am arranging an larger order of these gloves and they can make these exact gloves from synthetic leather as "special order"
They cost:
Size Medium 47 euros
Size Large 49 euros
Size Xtra Large 51 euros
Plus postage.
I can not give any exact measures about sizes, sorry.
You just have to figure it out yourself...
Or if you have a retailer somewhere near that carries Fairtex, you can go and test the FGV15.
