But camo is only a tool to make you less visible.. it will never make you invisible, so unless your going on special ops, I'd simply buy the camo that looks nice..
I love flecktarn designs myselfs, because they tend to work best. The DPM camo is very good aswell. I don't like oakleaf formed camo patterns like american, french, russian woodland etc.
