My friend Sharon asked me for recommendations for a lightweight, waterproof, motorcycle glove for a slender hand. Here are two fantastic options.
Revit Summit H2O
The first glove pictured above, is the Revit Summit H2O. Fully waterproof, and not very warm. Just a waterproof membrane. They're a really great all around glove and are one of the best women's priced at $134.99. It has a non waterproof version, but unfortunately they're going away so size/quantities are limited. You can check out my review of them here.
Rukka Vilma Gore-Tex
The second glove is the Rukka Vilma. I love the Vilma because it's a Gore-Tex Xtrafit glove. That means the membrane is bonded to the leather shell. Feels just like a lightweight, leather glove. Hard to tell it's even there!
