Prometheus Design Werx randomly releases outdoors-oriented patches, usually on Wednesdays. They have an archive somewhere to give you an idea.

PackConfig has similar style, not as limited releases.

This "Awesome Mix Tape Vol. 1" looks just like the one I bought from Amazon (random seller, listing no longer active), and is my favorite patch (excellent quality). I just got this "Stay Rad" throwback 80s patch from MilspecMonkey on Amazon, really nice quality so far, I think they have a bunch of mil- and non-mil patches.
