Barcelona soccer players slowed down by new sweat-soaked Nike shirts

BARCELONA, Spain - Few opponents are able to slow down Barcelona's squad of stars, but Nike may have inadvertently managed to do just that — with shirts that absorb too much sweat.

The Spanish champion says it has recently met with Nike officials to complain about the first team's new shirts absorbing so much moisture that they take on added weight over the course of a game.

Spanish newspaper El Pais first reported claims from Barcelona players that the shirts more than doubled in weight by halftime.

Nike said in a statement to The Associated Press on Tuesday that it is "working to find a solution to the problem with the shirts along with the club."

The sportswear maker said that it still didn't know the exact problem with the shirt, but that it should be resolved in two to three weeks.

The new shirts are made from a fabric called Dri-FIT, which is composed of recycled plastic and used exclusively by first-team squads of Nike's sponsored clubs, which also include Manchester United, Arsenal and Inter Milan. The jerseys are not for sale to the public.

Nike said Barcelona is the only one of its sponsored clubs to complain so far, although tennis star Rafael Nadal also experienced a similar problem with his own Nike Dri-FIT gear at the Australian Open in January.
