Let's see,
This one is really close too but more expensive
That really seems to be the closest I can find. I couldn't find anything in a darker color sadly :(
Poncho (black option obviously)
Gloves
I'm fairly certain it's not the same one like in the show but it's good enough
The poncho I bought was this one. The only problem is that it comes with white drawstrings to close up the poncho but I cut them off and I think it works great!
