I have recently purchased similar style briefs from four different companies. These are the best looking and most comfortable ones of the bunch. I will definitely get more.

Great boxer and love the way it feel. My crotch doesn’t feel tight. My wife loved the way it looked on me. I might have to order more. Thank you guy for making them.

I've been getting ads in my social feeds for a few weeks now and thought I'd give these a try. I'm not unfamiliar with horizontal fly underwear. I've been a long time buyer of another upmarket/fashion brand of men's underwear that exclusively offers the horizontal fly. On the plus side, after using horizontal fly underwear almost exclusively for the past 5+ years, I'll never go back to anything different. UP's horizontal fly is good, but quite a bit looser at the top than my other brand. This is good and bad. Makes for a bit more "forgiving" pouch as the elastic at the top of the fly isn't so taught, which means that access and drop down is a bit easier, but it also means that the front of the underwear feels a bit less secure, even baggy.

The camo pattern is really striking. It is unique, and distinctive. This is the biggest reason that I decided to purchase. These are just plain good looking boxer briefs. The embroidered "UP" on the left leg is also very nicely done, double sided, so it is smooth on your leg and you don't notice it. Fit and finish of the underwear is also excellent. I didn't notice any loose threads and the stitching was done with care.

The waistband isn't all that impressive. It is a bit shorter than I like, it could be 1/4 in, taller and it would be more comfortable and more the style I like and would probably reduce its tendency to roll. It is a bit less stretchy than I like underwear waistbands to be. So, if the waistband rolled less, so had a bit more vertical strength, and was a bit stretchier, and a bit taller vertically, it would probably be perfect.

Leg length was not what I expected. The product I saw in my social feed looked like a fairly long leg boxer brief, based on the influencers" that I saw. I was estimating a 7" inseam, but these seem more in the line of a 5-6" inseam. I haven't measured. So, at this leg length, these do have a tendency to creep up my leg through the day. If they were a 1/2 inch longer that probably wouldn't occur.

The inside leg and crotch gusset is a nice feature. Not only does it give the inside legs and crotch area a bit of stretch, but it is a mesh material and really is affective at keeping things cooler down there.

I wish I could give these 5 stars, and maybe I should give them 4, but there is some fine tailoring of the overall design that UP needs to consider. Specifically sourcing a different waistband, making the horizontal fly a bit less "baggy", and maybe increasing the overall length.

I'd like to see other varieties or underwear cuts. Right now they are selling just one cut, but in a whole bunch of different colors. I hope these guys remain in business long enough to expand their line or make improvements to what is a promising product.

Nice material. I ordered 4 different pair in medium, they do run on the bigger size, so I ordered 5 more different colors in small. They fit great so order a size down

I have other pairs. Will buy from them again.
