The pair of underwear I am reviewing is the Jam by Rounderwear Gold Brief in White (also available in black).  Before trying these on, I enjoyed the feel of the micromodal fabric as I took in the overall style and construction of the brief.  The fabric was soft and stretchy with two strips of piping running along the left and right side of the pouch.  The waistband is approximately 2 inches in width with a stylized cursive Jam scrawled across the right hip area and stitched into the gold elastic.  This is my first pair of Jam underwear and I enjoyed being able to try them.

Could this be the perfect pair of underwear?  Let’s see!

While wearing this pair of underwear, I went about a normal day of traveling to have lunch and shop an hour away from home.  I worked around the house a bit before leaving, drove an hour to lunch and ship, and drove an hour back home to relax.  Overall, I spent about twelve hours in this pair.  It was a busy day filled with lots of varying movement and activity.  The pair fit well around the waist without being taut like a lot of underwear companies are doing recently.  It was very comfortable all throughout the day.  The leg openings were quite comfortable and stretchy enough to conform without being too tight with a slim piece of piping that I first thought was just the fabric turned over and sewn against itself.  The pouch consisting of two pieces of fabric sewn together with a center seam is soft, comfortable, and conforming.  The pouch is constructed of two ply fabric or it would have been a bit see through and not as comfortable.  The fabric is 92%Micromodal and 8%Lastane and extremely soft, conforming, and like wearing nothing at all.  I liked that this pair covered the front area fully and just covered the rear enough to create a very nice look from behind.  These would be a great pair for low rise jeans due to the smooth fabric, conforming nature, and lower rise around the waist.  The crotch area is rather slim, which I love, where the pouch and rear meet and fits tight to the body holding the pouch and manbits in place quite well.  I believe this pair would hold up well during normal and active use.
I received a size large in this brief.  This size should cover around 34-36 pant size.  Sizing was true to size which I love in underwear.
I loved the soft fabric (I have not seen such nice fabric since a few reviews ago) as it was stretchy and conforming to the body.  The pouch was adequate and should accommodate average guys without any major issues.  The leg openings were comfortable.  The way the crotch area felt between my legs was nice and fit well.  The bold Jam logo looked nice around the gold band and created an expensive look.

Overall, this was an excellent pair of underwear and I felt sexy and comfortable while wearing them.  Jam seems to be a company that creates underwear that is rich in design and fabric while being functional.

So, is this the perfect pair of underwear?  Yes.  Yes it is.
