Olympic bobsledder Lolo Jones is trying on the suit that the U.S. team will wear in Sochi on Wednesday, and it is skin tight.

The suit was designed by Under Armour — which made similar aerodynamic suits for the speedskating and skeleton teams.

It's made out of UA's Coldgear compression fabric, according to the Baltimore Sun.

Lolo's teammate and gold medal contender Elana Meyers could barely breath. As Lolo's Vine shows, it's not quite as glamorous as it seems.
