Wasteland Cowl Olive Green by Crisiswear on Etsy may not seem like much, but that little bit of protection against the elements is a big thing. You get yourself a neck guard, hood, and part of your chest protected.
I like this wet side setup. The main thing I'd change is add a 30"x96" stainless steel sink, plus a smaller sink for mixing chemicals, washing hands and developing and rinsing film. The large stainless sinks used to cost a fortune, but used ones are cheap now. ~Camerosity
