Do some digging. I swear I saw full Sitka rain suits for like $100 a piece earlier this year at bass pro.

I’m not as worried about waterproof as I am stuff that dries really damn fast. Merino wool socks FOR SURE. Spring for merino wool underwear and baselayers if you can afford it.

I have two pair of Sitka pants and wanted a third this year. I decided to try a cheaper amazon option and fell in love with these pants. They are waterproof too. Buy these waterproof hunting pants

As far as a rain jacket, there are a shit load on amazon for under $60 a piece that will work. Doesn’t have to be camo.
