Swim shorts for men

Tri shorts are good for swimming, biking, and running and can be worn under a wetsuit.  They have a thin pad that dries out quickly for biking and doesn't get in the way for the run.  Chlorine will damage them in time, so while an occasional use in the pool is okay, they shouldn't be your standard training attire for pool swimming (many recommend jammers for pool training).  You'll get a lot of opinions about best brands, but a lot depends on the individual for fit.  I have had good luck with DeSoto, but I am a Clydesdale - your physique may be different and suited better to other brands.  Good luck!
