These kind of remind me of a speedo with short legs attached, very short, but that's what I was looking for. They feel good after only one wash, have only had about a week, so I've only been able to wear once. Hopefully they are similar quality to other UA boxer briefs, if so they will last a good while.

The UA Men's Performance Tech 3" Boxerjock are a great fit. I like the color selection as well. The material is very comfortable and feels great. I have ordered these now for a couple of years and I am really fond of this style.

I usually wear the 6 in fitted under my 5in running shorts and it works good and doesn't stick down maybe a little while sitting , so I decided to try the 3in for my running and a lil shorter so not visible ever; now I don't usually chafe with the 6 in only once in a very long while and im hoping the 3 in is the same idk yet, but any brief does chafe me on long runs so I can't do briefs, anyway I hope these work I ordered today
I order these thinking I would get a three (3) inch inseam. What showed up was a inch and half (1.5) inseam at best. Not even close to what is described in specs for them. I will not purchase these again
Recycled polyester isn’t as nice or as soft. It is thicker and tighter. No longer made in Cambodia which has changed the feel of the size. Disappointing
these 'new' boxers are improved compared to the last version. The previous models's fly opening was too wide and caused your Peter to poke out of the fly panels, this new model fixes that.As is, they are literally perfect, light and breathable, supportive during sports yet comfortable to lounge around in.I bought a few pairs and love them ... I noticed most sizes are already out of stock. Why such limited availability? am I gonna have to wait another 3yrs before they're available again?
The 3 inch inseam is perfect for mobility and fit. Soft comfortable waist band and materials. The legs stay in place and do not ride. And my favorite thing about Under Armour is the very convenient fly front which almost no other major brands offer.
I bought these a few weeks ago for when I workout. I am really impressed! They are so comfortable and provide great support. I would highly recommend!
I've been wearing u.a. clothes since they started and these are the only product of all the products they produced over the years that are still my favorite and are still being produced today. I go up 1 size because their a little too tight . What I love about these is that they don't have seams on the back side, so they are very comfortable, especially when sitting. I would like too see U.A. come back with the ones that came in the bright colors ( bright neon green and the bright neon red that they called isotech , if I'm not mistaken).U.A. discontinued a lot of great products that I thought were better than whats being produced now and can't understand why.
