First, I will say that the material is a little nicer. Second, I believe the low rise/ no fly design is a definite improvement. No looking back there, as it certainly makes things easier. I didn't have an issue with them riding up my backside. I thought the fit was fine.

I was looking for something cooler and more comfortable, but didn't find it here. I don't mind paying more for quality, but I simply can't justify the expense here. If I'm going to pay this price, I expect a noticeable improvement in being cooler. The difference was minimal at best with these.

No problems with shipping
