The surplus stuff here is hard to find and often of poor quality. It seems the Quartermasters have a habit of rendering everything as unservicable as possible before sending it to auction.
The "Tacticool" stuff tends to be overpriced and often of poor quality too.

I but good quality civilian gear and I usually choose muted colours. My colour choice is more about aesthetics than for camo. Bright colours hurt my eyes.

I deliberately go for bright colours during the hunting season.
If I was looking at it from a survival point of view I might want bright colours so I was easier to find instead of hiding.
I really don't expect to be in a situation where I need to be evaiding enemies.
