What I have a lot of is hunting clothing. I like having 2 or 3 of everything I use all the time, so I have clean all the time (don't have to run a washing machine after a long hunt and then hope to have them dry by morning). So, I have 2 pairs of mid weight bibs, 2 camo fleeces, etc. When I was buying clothes last year, I was always like $5 from free shipping, so I would add a pair of liner socks to orders. I now have like 20 pair of liner socks
A lot of my other gear was just bad ideas or things I wanted to try out but I didn't like it. For instance, I have 4 ways to hang a bow from a tree. I'll probably pick my favorite this year, but I have them.
