The pockets are not of greatest quality. I usually start to see the pocket's stitching fraying after about 50 dives, by about 100 they are already useless. In some pairs I managed to repair them to extend the usability time, if the cloth is in good condition.
So, for me, a pair is useful for 3-4 months. I still got a pair but it's the last one I'm gonna use before looking for better alternative.
I don't hold too many things in them- ems scissors, wetnotes, some double dogs and small spool.

Interesting. Mine have got over 250 dives on them so far and look pretty much the same as when I first wore them. I usually have a spool and DSMB in one pocket, and a back-up torch in the other. Be good to see how long they last, though if I can find a better-fitting alternative, I will move to them.
