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 definitely can't say that these are cooler and more comfortable, because they aren't. 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
