Underwear with a zipper is meant to be unzipped, and trust me, after 10 minutes you’ll be dying to unzip them. Ideally, it will be your lover who is doing the unzipping, though. Even though these look fantastic, they are far from the most comfortable underwear you will wear. I purchased the L/XL size. I usually wear between a 34 or 36 inch waist for pants and underwear. I don't particularly care for the boyshort cut of underwear, but my wife loves the look so I wanted to give it a try. For me, the style of the cut just isn't very comfortable. The cut of the pouch is what is actually the most uncomfortable. Believe it or not, I think it needs to be larger. It's kind of like wearing jeans that are a little too tight, you'll find that you need to constantly "adjust" yourself. Of course, once someone pulls that zipper down, you'll find it's far more comfortable.

The material of the shorts is very soft, and is a nylon/spandex blend. It is machine washable, but should not be dry cleaned. It also stretches pretty well, so if your waist size changes a little over time, it should still fit without much problem. Surprisingly, the boyshort cut prevents the underwear from moving up on you so you don’t have to worry about wedgies. The fabric is also very smooth and doesn’t chafe. I expected the ring on the zipper to get in the way since it is quite large, but it usually stays out of the way and isn’t noticeable. The zipper is pretty sturdy and didn't fall down at all after several hours of wear. The zipper itself could be a danger if you have hair to pull out. I didn’t have this problem as I am usually clean shaven down there. Thankfully, there is a flap of fabric that is supposed to be covering the zipper and protecting your sensitive areas. If you are moving around in them, the flap may occasionally get pushed to the side and you’ll feel the metal zipper, and you will have to once again “adjust” yourself back to normal.

The effect of wearing the Zipper shorts is what is most important, in my opinion. You are not going to be wearing these shorts for normal use during the day, mainly because they are not that comfortable. Instead, you will most likely put them on before starting a romantic evening with your significant other or sliding them on as a surprise when no one is looking. From my experience, seeing your wife or girlfriends eyes light up when she sees these shorts makes it all worth it. Naturally, seeing that zipper just begs to be pulled, and no matter what happens after that I am sure that it is worth the price.

I have only worn these shorts a couple of times. They were a little tight for me. I wish that they came in a larger size, because then they'd be perfect for me. Both times I've worn them they have done exactly what I wanted them to do; get my wife to pull down the zipper. So far, the Zipper shorts have had a 100% success rate for getting blowjobs. Since the first BJ was a little longer than the second, I'm going to have to ration their use and not wear them too often. So far they've held up great, and I hope that they stay in good condition because I want to keep the record going.

I found that if I wear them lower on my hip, I have more room. Sadly, these no longer have a 100% success rate in the bedroom, but still very effective at getting attention.
