Nike is working with Barcelona to resolve the problem of its sweaty shirts. Barca contends the shirts absorb too much moisture and take on added weight during a game.
The new shirts, not available for sale to the public, are made from Dri-FIT, which is composed of recycled plastic and used only by Nike-sponsored clubs such as Manchester United, Arsenal and Inter Milan.
According to Madrid daily El Pais, Barcelona players claimed the shirts more than doubled in weight by halftime. Barca is the only team to complain. Spanish tennis star Rafael Nadal had a similar problem with his own Nike Dri-FIT shirt at the 2011 Australian Open.
