The hot pink gloves are from Reusch, who have been the US team supplier for a while.
As a number of suppliers do (e.g. Spyder), they come up with a new version of their product, just so it can be featured at the Olympics.
The Austrians still seem to have the old-style "Samurai" Reusch gloves though. And there's apparently a yellow / slightly-greenish version, which may be the women's or something.
