Your not alone LOL, I noticed the same thing. I love the Obsession pattern. I used to get it at Wal-Mart and now they sell another pattern in the spring. Seems like the only places that have it now are the high dollar company's, with their own special version of a stretch/ moisture wicking fabric. I just like the plain old cotton long sleeve shirts and 6 pocket pants.
The new Midwest Turkey Supply catalog has a decent price on this style of pants and shirts. That's propably where I'll get mine.
