The simplest technique for winter protection of young figs is to tie all the branches as close together as possible, surround the tree with some fencing, and fill the fencing with fall leaves, straw, or other available materials to provide insulation. Plenty of fall leaves to be had right now- check your neighborhood on trash day if you don't have enough on site! If available, a tarp can also be placed on top. It is okay if some of the branches stick out. If we have a mild winter, those unprotected branches will be fine; if we get a harsh one, you'll simply cut them off in the spring after growth begins.

Another easy method for protection is to tie the branches together and surround the whole thing with an old carpet. Layers of burlap, row fabric, or even old bedsheets can also be used, although make sure to attach them securely so they don't blow away. For older, bigger figs, you may need to wrap individual trunks/branches with this kind of insulation to protect them.
Wrapping figs with fabric can help with insulation and protection from winter winds. A south facing wall also helps to create a warmer micro-climate!
At the very least, pile mulch or other material around the base of the tree to protect the roots (NOTE: this will keep the fig from dying altogether, but may not preserve your harvest for next year).
For extreme cold protection (up to zone 5),
some growers actually bury their figs for the winter. A fig "grave" is dug on one side, then the roots are severed on the opposite side and the whole plant is lowered into the ground and covered with the excavated soil!
