I was thinking of getting a set of Sheex, but they're awfully spendy. They're like $185 for a fitted sheet, cover sheet and four pillow cases (two extra) and this price is 25 percent off the regular price, which is $250. The advantage of these sheets, purportedly, is that they are cooler to lay on in the hot summer months, are self-wicking, and supposedly "ridiculously soft." Anyone ever try them?
