UGG began life in the late 70s on the beaches of Southern California when brand founder Brian Smith offered surfers and beach bodies comfortable and practical sheepskin boots. By the mid 80s, UGG was synonymous with relaxed, Californian cool thanks to the brand's signature boots being adopted beyond the beach. Today, UGG boots can be spotted on the feet of some of the world's most recognizable celebrities, testament to the brand's far-reaching and fashionable, casual reverie. When it comes to weekend dressing, take it easy with UGG sweats. These cozy, reach-for styles will keep you snug and looking great whatever your pursuit.
