IMHO camo is highly over-rated as far as patterns go. I prefer regular old style military camo. If I find Mossy Oak or Realtree on sale I'll use them.
As long as you match the colors to the terrain, you'll do just fine!
I prefer cotton or other light weight fabrics and use them as an outer layer only, as paying more for the camo design on underwear is just plain senseless!
As are the so-called scent blockers which were created to separate hunters from their money!
It's not rocket science, and also some people are more concerned with what looks good in town instead of what works in the field!
