This Jock strap is a bit on the industrial side.  If you need a very strong garment that will not easily shift or break during use, it is great for that, But as far as comfort over a full work day goes, this garment is a bit on the rigid side of things.  the elastic is very strong, and as a consequence once it is in place it is not likely to move, but what is being held in place is also unlikely to move as well.  I would recommend this product for actual athletes, particularly if it is only going to be used 2-4 hours a day with an actual athletic cup, but for manual labor over the course of 8-12 hours look elsewhere.  I Will recommend this for very dynamic movers who need highly restricted movement over short periods of time.
