The are great short briefs for runners. If you don't like polyester compressions, these are the 2nd best option and a killer price, especially on sale. The slightly shorter 5" cut is great for summer runs. They wick better than any cotton for runners - 2nd only to Underarmour charged cotton at half the price. The top band is spandex. Size runs pretty true for me (med is good 32"). I suspect these aren't 'long lifers', but worth the 20 bucks for a 2-pack.

The Climilite Sport Performance is the same brief in polyester. That confuses people since most websites don't list that detailed.
