One of these - black knee length.
If so, I made a tailor-made extension section for when I was pregnant and/or carrying a small baby in a sling. I spent ages making it and if I say so myself it is pretty good - it's made of waterproof material, insulated, zips in to the north face zips and poppers, and has a draw-cord to keep your neck warm! It is even extendible according to how pregnant you are:)
Anyway, I'm not pregnant any more, and also done with having babies. If anybody would like it, it's free to a good home! I'll even post it to you!
