From the USMS:
Dear Tony ,
The FINA Masters Committee has recommended that the FINA Bureau, meeting in mid-January, approve its recommendation that Masters swimmers be governed by the same swimsuit rules as the elite pool swimmers. If the Bureau approves the committee's recommendation, it is anticipated it would go into effect after the Bureau meeting. If this recommendation becomes policy with the FINA Bureau, USMS will implement it for our sanctioned swim meets.
For the time being and until the FINA Bureau issues its policy for Masters, the June 1, 2009 ruling that allowed technical suits in USMS swim meets is still in effect. If you choose to compete in a USA Swimming sanctioned meet, you must follow USA Swimming rules. If you would like more information on purchasing technical suits, you may contact your swimsuit dealer or any of the following:
bluesevety, TYR, Speedo, Finis
After reading this letter two more times through, I decided to go for a bike ride at my local bike path.
