I read the reviews of the Mueller athletic supporter with cup. Those reviews are interesting in that
1.) one reviewer gave it one star because after months of use the stitching failed.
One wonders how long a supporter is supposed to last. If I wore garment for months I would expect failure.
2.) Another reviewer wrote it isn't for biking. Being an avid road biker, one wonders why anyone would suggest a supporter with a cup for biking. That is why bike shorts were invented.

This supporter is perfect. Unlike the others, the support is double lined and there is no free edge. No curling or wear is possible. Good fit, good support, and light weight.

This one is for people who don't want a cup. It is perfect for jogging or other sports.
