UGG has set the standard for crafting premium products from incredibly plush sheepskin. The mastery of this material in the fine craft of shoemaking is deeply ingrained in our rich history. For over 35 years, UGG has used only the finest, luxuriously soft Grade-A Twinface sheepskin in the world in our Classic boots, putting each sheepskin through an extensive process to ensure it will provide the signature UGG experience. We look for uniformity and a flawless, fine-grained texture with no visible defects. On the wool side there has to be an even “stand up” thickness across the entire piece. At six different points in our process we select, re-select and select again against these criteria ensuring only the highest quality sheepskin make the cut. The final product is a finished piece of sheepskin worthy of only the UGG Australia name.
