In the first couple wearings I can tell it will far outlast the lycra speedo jammers I'm used to. For practice I ordered a size up and am glad I did - there's not much room for my "stuff" and this fabric gives less than lycra.

they are great for lap swimming

This suit fits much smaller than other Speedo suits.

Well designed jammer with quality material; however, appears to be designed for swimmer physique not triathlete.  Bought up a size (34)based on other comments. Have a 31/32 waist and the 34 fits perfectly.   Bottom line...quality wins and thankfully I ordered up a size.

After buying a number of Lycra jammers that last about 3 months before they're see through, these were recommended to me.  So far they're great and seem to be much more durable.  One thing to note, they have a rather low rise on the waist.

These last the longest for me comparing to the other kinds we tried.  A year later my swimmer went up in size and I came back to get this one, because the others were stretching way too soon.
