In reply to thecruxclimber:
The ME Guide gloves are really good. I have them in XS. They are one of the few that I've found with short enough fingers to allow me to actually use my fingers to work with krabs, ice screws, place gear etc.
If your hands are really tiny then it might also be worth looking at kids ski gloves etc. TKMaxx is a good place to look along with Decathlon if you have one near to you.
