I ordered a first set last month and really enjoyed the moisture whisking and non riding up attributes.  I reordered another set for just every day sitting out in the TX sun and needing cooler underwear.  They came and put them on and totally different.  The first fit like a brief and these truly are tighter and fit like a bikini.  Not happy.  I went to put on my older pair and they are starting to unravel.  Both a disappointing.
