All 44mm PAMS are XXX/XX and 24/XX. Lug width is 24mm. the 22 after or 24 (whichever it may be) is the width at the clasp end.
Most of my straps are 115/75 24/22 - I have smaller wrists. The 115 and 75 are the lengths (in mm) of the straps the 24/22 is the other as described above.
There is a good post here about that, in case I didn't do a good job.
