    Comments about Kings' Court Performance Flex Boxer Briefs by:

    Ordered 2 pair in size 3X in different colors. There was a good 3 inch difference in the elastic waist of the 2 pair. I had a 3rd pair on backorder and I cancelled it due to fact that I had no idea what size the waistband would be.

        The waistband was so tight, it caused a rash. If it were not for that, the boxers were very comfortable.

          Boxer briefs comfortable hold everything in place true sizing. The only negative thing is the waistband breaks down early in the lifespan of the underwater.It begins to shred and elasticity goes away.

                These underwear are excellent except that the waist bands are coming apart starting at the seam. Other than that they are comfortable and great in the hot weather and while riding my Goldwing and everyday. Just hope they last a while. I even bought an extra few pair in a larger size thinking it was my weight causing this; but same thing. I am glad I tried them and just hope the quality will get better before I need to replace them.

                    I sweat a lot, and bought these to lose the "damp feeling" associated with wet cotton underwear.
                    I found them to be sure fitting, comfortable and they stay "dry feeling" even when soaking wet from sweat!
                    Great for those who, like me, sweat or for the athletic guy who wants to stay dry.

                          These boxers were not as comfortable as I expected them to be. By the end of the day I experienced a rash. After only one washing the waistband seemed to be falling apart.

                                Stitching is poor on some, but best on the teal color, where the back looks to have been overstitched. On steel and black, the waistband is already coming apart in the back, and the elastic is shredding--almost like the final stitching was not completed.

                                I bought these for my husband and after only one wash the elastic waist band is unraveling and the elastic bands are breaking. Horribly made. Very dissatisfied. Especially for $20 a pair!

                                  Great product. The waist is a little large compared to the leg openings. I ordered the size that should fit me and the legs fit great but the elastic waist is just a tad too big...
                                  Other than that I really like them. They're soft and comfortable and provide some fabric between the legs to help with chaffing.

                                      These are the best. Leg opening isn't too tight like others. They are cool and comfortable.

                                        I am tired of paying high prices for big name brand boxers, so I tried Kings Court. They fit well, and are very comfortable - but - the waist bands do NOT appear to be machine sewn to the body. I am afraid that when the fist stitch fails, the waist band will come off - and the shorts will be unwearable.
