History
The 2009 Games were held in Vientiane, Laos where the records for 25 events were broken. Of these, 12 records were broken by Singapore, eight by Malaysia, two by the Philippines, and one each by Indonesia, Thailand and Vietnam. However, most of these records were broken while non-textile swimsuits were legal for use between February 2008 and December 2009. They have since been banned in January 2010. To date, 5 records set using the non-textile swimsuits remain in the record books.Men
