"I have been wearing this style since it replaced the X3D and thought it great. Very soft, comfortable and well made. Now Ergowear have redesigned them to remove the back seam. I really don't like this as I prefer the definition that a back seam provides. I do hope this change doesn't affect other Ergowear mini boxers"

"- and so they should be at that price! Fit like a second skin but smooth and silky. Really comfortable and true to size . I'm 35" and chose L which are perfect for a close, but not tight, fit"
