In a small bowl, combine fig jam, mustards and orange zest; set aside.
In a small bowl, combine brown sugar, garlic, rosemary, salt and pepper. Season pork loin with brown sugar mixture, rubbing in thoroughly on all sides.
Heat vegetable oil in a large skillet over medium high heat. Add pork loin, and sear both sides until golden brown, about 2-3 minutes per side.
Starting on 1 side, lay a slice of bacon, crosswise, on top of the pork, laying another slice to slightly overlap the first. Continue with remaining slices until fully covered.
Place pork loin into a 6-qt slow cooker; top with fig jam mixture. Cover and cook on low heat for 3-4 hours, or until completely cooked through, reaching an internal temperature of 140 degrees F.
Serve immediately, garnished with rosemary, if desired.
