Great fit - I'm not gonna lie, I was hesitant on buying these (seemed too feminine for my liking). I bought them thinking the briefs were a good fit that I previously bought, the feel in the ball pouch was nice... these though - - wow. Such a confidence boost and great feel!! :)

Yes they are! These are some of the most comfortable underwear I have ever worn. I noticed others talking about how great they were and I was not disappointed! They are not restrictive, yet provide support and are super soft to the touch. I love my Saxx underwear. If you are considering buying, I recommend getting a pair! The fit was true to size. I usually wear a 32 waist in pants and the medium size underwear fit perfect.

These are a fantastic cut and fit with that "ballpark" feature that really makes them stand out with a tight but supreme comfort. Great quality of craftmanship and likely to last a long time, like all my other Saxx underwear. I'm giving it 4 stars because viscose is not the most breathable or fast-drying of materials plus it easily absorbs sweat and odors. So I would change these every single day or right after a workout whereas my merino wool underwear I can wear for 2 or 3 days even in the summer. Given that these are half the price however they are still decent value for money.

Three years ago, I replaced my entire underwear drawer with 8 or 10 of these briefs and they are still holding up flawlessly. When it comes time to replace them, I will be sticking with the Ultras. They are "forget you're wearing them" comfortable and the material is high quality. Along with the Kinetic boxer briefs for workouts, these are all I wear.
I was not aware that this was the level of quality and support I should expect from an undergarment. Truly reset my expectations. I immediately purchased additional products so I never will have to wear an inferior undergarment again.
The feel is ok. The material is ok. The fit could be better ... pinches when sitting too long. It is nice to have underwear that helps hold the junk in place. Most underwear is not designed for men. Hanes men's underwear is designed for women. No support and if you have a good package, the material is never enough to keep things in place. I guess the biggest negative is the price. It better be beyond expectations, fandamntabulous if I were to buy them again ... so nice try, but still work to do.
I have the boxer briefs from Saxx which are great but thought I’d try the briefs for a change. These are hands down the comfiest underwear I’ve ever worn; so soft when you put them on and then they keep your bits so cool and supported during long days out trekking in the summer. Will be ordering a load more!
I'm not a big fan of boxer type of underwear.I'm so tired when it keeps riding up my thigh, especially when I travel on the car or airplane seat for a long time.I know that there are plenty of brands that offer the same style and might be cheaper, but SAXX Ultra Brief Fly uses a Breathable, Soft, Cool Touch fabric. Plus the signature 'BallPark Pouch' that keeps everything in place.With all of these features, This is the best comfortable brief I ever had. I will never go back to regular underwear ever again!It is highly recommended!
Found these on a deal on another men's underwear site, stated to be their best seller so decided to give them a try. No reviews on that site so I came here to look at reviews. Based on a few that said they run large, I sized down. The waistband is too tight and the pouch is too generous to be supportive, hence, the unusual sizing. Not what I expected from so many good reviews. The fabric is very soft and feels nice but had much better expectations.
Very soft, fit runs a bit on the large size, so would recommend sizing down one size if you're in doubt (this might be a personal preference kind of thing - I prefer underwear with support, rather than loose). Odor resistant; great for everyday wear. One of the first products I tried at SAXX, and still a regularly used product. WIll be downsizing to XS for better support now that I have become aware that XS is available; thank you SAXX for providing this - not many underwear retailers do!
