Review on Innovative Haus Competitor 40: Disposable Resistant by Doug Cardello

While the statement that they are 45 denier and thicker than other types is true I don't know what the non slip part has to do with that. The white markings on the bottom seem to indicate it's a non-slip piece, but it's just screen-printed. Also, they seem to hold up much better than the others and the ribbing around the upper isn't as flimsy. I've only used a few pairs so far so we'll see how well they hold up.
