"For late fall and early spring riding conditions, there’s Sturmfist 5. A water and wind resistant Polartec Neoshell on the back of the hand meets a layer of water resistant Pittards goat leather on the palm to ensure the utmost protection against the elements."
"WATERPROOF-BREATHABLE MEMBRANE An ultra-thin sheet of microporous material behind our textile shells keeps you dry and warm in the harshest weather conditions. Liquid water molecules from outside of the garment are larger than vapor molecules created by body heat from the inside. The microscopic pores are smaller than liquid water molecules, but larger than vapor molecules. As a result, waterproof-breathable membranes stop liquid from the outside, but release vapor from the inside for thermal and moisture regulation. "
