I bought these Guard Hydroshorts.  Looks good and fits great, but I took others advice and ordered a bigger size than normal.

If you're over 6 feet these trunks will probably feel too short.  I have two boys that lifeguard - one is 6'3" and the other 6'6" - and they looked like girls shorts on them.  Quality great though, we have the longer version and they lasted very well.

The life quard suit is short.  So short we are actually going to return it to swim outlet.

They fit,.
They're not board shorts baggies.
They're not speedo briefs.
Perfect for swimming laps in pools.

TYR Guard Hydroshort definitely run small.

This suit is everything it says it is in it description. It is fairly short, but that is what I was looking for. The price is good. I bought them in exchange for another item, which swimoutlet.com handled in a friendly, prompt manner.
