Universal Jacket Extender by Make My Belly Fit. It is water and wind resistant. You can use it from early pregnancy (zipper extenders only) through to the end (zipper extenders + center panel). Plus, you can flip the center panel and use it while baby wearing - you can have your baby in your jacket and you can both be warm! NOTE: This is not a carrier, you still need a separate carrier to hold your baby. Comes with a fleece panel and a polar fleece/sherpa-esque panel that can be buttoned in for extra warmth. Originally came with clips to help keep the zipper extenders in place, but they did not work well and most eventually got lost, so I just used safety pins to secure and it worked just fine. EUC.
