Question: what is the difference between koolaburra and classic uggs?
Answer: UGG Classics also use twin-faced sheepskin, but the inside is then cemented to a cow leather outside to make it more durable. What you wind up with when comparing them side by side is a soft supple boot inside and out (Koolaburra) and a boot that is soft inside, but a little more rigid and durable on the outside (UGG).
