In a small bowl, mix brown sugar, garlic, dried rosemary, salt and pepper. Season pork loin with this mixture, rubbing on all sides.
Heat vegetable oil in a large skillet over medium-high heat. Brown pork loin on all sides by searing for about 2-3 minutes per side.
Let pork loin cool for a few minutes while you make the glaze. To make glaze, mix the fig jam, mustards and orange zest in a small bowl.
Wrap pork loin with bacon by laying one slice at a time crosswise over the top of the pork, tucking ends underneath the pork loin if able. Overlap edges of bacon slices partially. Continue until loin is fully covered with bacon.
Place bacon-wrapped loin in a slow cooker and top with fig glaze. Cover and cook on low for 3-4 hours, or until thoroughly cooked through with an internal temperature of 140 degrees F.
