As suggested always order one size smaller.i ordered large ,too large,I ordered small too small, I then ordered medium just right. My normal size with other brands is large. Pants fit well.

Love them especially since I have Lupus mainly of the skin I want a lot more maybe you could lower the price a little because I want at least 10 pair of them

I wish l had bought these before l bought another brand as they are super to wear easy to use when needed, fabric is great against your skin. Highly recommended.

Solid underwear

I like the Crossfly underwear. They are pretty solid. Not as soft as some other brands but they are solid and support well


Very comfortable will definitely be buying more

Incredibly comfortable and a quality product.


So far so comfy. Had a pair of crossfly’s before and they were comfy but these Pro 7” are even more so. Will definitely be after a couple more of these soon…


So good I bought some more

The best….

These boxers have to be the best I’ve ever worn!

bought both Lg and XL sizes

As a person who is at the Top of the Lg size and the Bottom of the XL, I decided to buy both and return the least like size. After getting them I wore them both and like the little differences in size and feelings while wearing them. So I have kept both sizes and I am very glad with them both. The Large is a snugger fit and such. The XLarge is a little looser and both are very comfortable when exercising in them.

Bought Lg and XL planning on returning the size least liked.

I originally bought this 3 piece bundle in XL. I was called about 2 hours later by CrossFly customer service asking me what size pants I wear. To which I said, 38. Then he suggested that I change my order from XL to LG, which I agreed to. Went I received my order it was the XL. I tried one pair and found them to be a little big. So I contacted customer service by e-mail about it and the fact that my account invoice showed and error. After contacting them, I was contacted back about already shipping the LG bundle out and cleaned up the account billing. I received the LG tried a pair of them and indeed they were a little tighter than the XL. However I struggle with which size to keep and contacted customer service about rebilling for both orders and just keeping them both.

I kept both sizes as I at times like a little looser fit and at times I like a little tighter fit. So these did the trick and being such soft and comfortable material, I did see where I could go wrong keeping both pairs. I have worn both sizes several times each and I am more and more please with my purchase of both sizes.

Thank You CrossFly for such nice men's underwear.
