LONDON (AP) — When temperatures dropped into the low 60s for the first Olympic beach volleyball night session, Kerri Walsh Jennings and Misty May-Treanor said bye-bye to their bikinis.

The two-time defending gold medalists from the United States wore long-sleeved shirts on top of bikini bottoms on Saturday, when the temperature at the start of their 11 p.m. match was 63 degrees. Their opponents, Australians Natalie Cook and Tasmin Hinchley, wore long pants and short-sleeved shirts underneath their bikini tops.
