DiMarzio ClipLock straps, with the world"s most secure and unique guitar strap fastening system, have been a favorite of Steve Vai for many years. Steve has grown fond of the Italian leather ClipLock® strap, so DiMarzio worked with him to design a custom Vai logo to grace his signature strap. The Steve Vai Italian Leather ClipLock Strap is made from thick Italian leather using a special tanning process that makes it incredibly soft and flexible (or for Steve, is it flex-able?). It feels like an old friend the first time you wear it.
