I've worn ComfortSoft boxer briefs for nearly ten years.  In that time I've experienced three variations:

- Super soft, thick fabric with perfect fit.  These have the waistband tag toward the left side and last for years before needing replacement.  Sadly. I don't think these are sold (or easily located) any longer.

- Thinner fabric,  but still soft with a perfect fit.  These don't wear as long as the thicker boxers before needing to be replaced but are still good underwear overall.  The waistband tag is in the front center.  My most recent order from this seller was of this type.

- Thin,  horribly scratchy and constricting that's almost a full size too small.  Confusingly, the waistband tag on these is also toward the left side (similar to the super soft ones above) but these aren't even fit to be polishing rags IMO.  I bought a 10 pack of these and tossed them all in the garbage after giving them three washes in the hope they would soften up.

So the good news is this particular 5 pack still appears to be decent quality.  Not as good as they used to be years back,  but certainly good enough.
