Read more:

Our athletic boxers were designed with careful consideration for the needs of the big and tall athlete. Just like you, we're not messing around when it comes to underwear: moisture-wicking fabric keeps you dry and odor-free, and open hemming and wide legs provide you with the freedom of movement you need to perform your best. Chafe free fabric adds to the comfort, because you have bigger things to worry about than your boxers -- but having a quality pair like this is nice.

 

Reasons to Buy:

Our customers love these boxers, saying they're so lightweight and soft they feel like they're wearing nothing at all.

Best Boxers I've Ever Worn!

    Comments about Kings' Court Performance Flex Boxers by:

    Keep selling these! These fit me more like boxer briefs than boxers, but I'm at the top end of the size range and always looking for more room. The fabric and stretch are both comfortable and practical. I could use a bigger size than a 7X with more rise on them, but once I got these on, I didn't want to take them off.

    The only down side is that the front seam started to pop the first time I had them on. I'm going to stick with them anyway for the comfort level. Orange is OK. Gray is very nice! Red, White, Navy would be good colors too.

      Comments about Kings' Court Performance Flex Boxers by:

      These boxers are the most comfortable I have ever worn. I have worn cotton briefs for years and on a whim I bought one pair of these boxers with another order. I was amazed at their comfort so I ordered 5 more pair. They are cool and I do not sweat nearly as much as I did with the briefs. The elastic waistband is wide and keep them from sliding down. So far I have washed them about half dozen times and they are holding up well. The color has not faded. Plenty of room to move and I hardly know I am wearing them. You can't go wrong with these.

              Comments about Kings' Court Performance Flex Boxers by:

              I've the previous version of these and they're awesomely comfy. So I ordered a few more pairs...when they arrived they were noticeabley different. The body of the underwear is fine, its the elastic waistband that is the problem. It's like they put on HALF of the elastic for my waist size. It felt like they were cutting me in half...an keep in mind I ordered the exact same size as before.
              Very disappointed in this, as usual KSD can't keep anything around long enough for the customer to know if the cut an fit is going to be same/worse/or better.

                  Big fan of the performance flex underwear. I've tried the boxer briefs, bicycle shorts, etc. These are great for someone with a large "front end". Comfortable. I hope the waist bands hold up better than the other styles have for me.

                    I got these for my husband, because of the material they are made of is his favorite. When we first got them we had to laugh they where HUGE (My husband is a m/l). I was about ready to return them, but my husband talked me into keeping them. Good thing we did because they are the only boxers he wears now! Have had no problem with any of sems and they have been washed well over 6 times!

                          It's so sad to purchase a garment, then have it come apart at the seams in the FIRST wash! If my doctor did not recommend I wear an oversized boxer to sleep in, I would never purchase Any of these boxers sold here. (I have had the same issues with the cotton ones as well.)Looks like its back to my sewing machine. Don't waste your money.

                                I like the idea behind these boxers. I like that they are cut bigger, and have some stretch. Shorts like these fit me better when the rise is about the same length as the width. These are approaching that in proportion. I wish you'd also offer a size-8X and 9X in these. Fabric feels a little too lightweight and flimsy, and I wish they were sturdier and felt more like a man's boxer short without having to resort to cotton. Thank you for working to improve these, they are the kind of underwear I have been looking for a long time now.

                                      Nice product, but after two washings all the waistbands are starting to fray. Significant durability issue means I cannot recommend; it's a shame, though, because all other factors are very appealing.

                                          I think they have improved over the first ones that I purchased. These appear to be more durable better sewing and will last longer.

                                            Very disappointed in the quality. After 2 weeks of wash & wear the material ripped away from the waist band. I had to toss them in the trash.

                                            For the last five years, I will use no other underwear. These are fantastic in every important way. Try them please ....
                                            You can count on the sizes being true to your needs.
                                            Only thing you CANNOT count on is King Size always having them in stock.

                                            Other than the poor quality that we have come use to with KING SIZE products, and pretty much every other line of clothing made for the Big and Tall man, these are ok. The main fabric is very comfortable and has stayed that way through many washings. The biggest issue is that the elastic in the elastic ban, just falls apart very quickly. Especially at the seam in the back. A little extra stitching in the back would probably take care of a good part of the problem.
