The Sleeping Bag Coat is a Norma Kamali classic. Since its inception during a camping trip in the 1970s, the SBC has remained a beloved winter essential and long lasting collectable; swaddling its wearer in warmth and head-turning style for nearly half a century. Other puffers come and go; the longevity of this iconic coat is a testament to its innovative design.
