Anything that fits from Gabe's . Except the brands that donate to immoral causes.

I have an old pair that probably cost $15 but increased in value since the knees wore through. As soon as I get motivated enough I plan to rip the seams, make a pattern from them and use my own mil spec NYCO camo.
It'll be versatile working on trees, hunting or town. Just glad that I live where camo is always in style like blue jeans.
