Liga - Barcelona weighed down by absorbent shirts
Barcelona may be forced into an embarrassing rethink on their new shirts after players complained they get too heavy with sweat.
The jerseys, specially designed by Nike to be eco-friendly, reportedly are made from as many as 12 recycled water bottles, and also employ polyester microfibres to keep wearers dry.
But despite weighing 200 grammes at the beginning of a match, the shirts are retaining water and can weigh as much as half a kilogram by half time.
According to Spanish paper El Pais, Barcelona players have noticed the problem early on their summer tour of the USA, and have been so concerned by the way it feels during matches that they have taken to putting the shirt on the scales during matches.
The paper also reports a player claiming that the shirt "stuck to the body like a limpet."
The club have called a meeting with Nike over the issue, with a spokeswoman for the company saying that testing would now take place to assess the problem.
"Nike's product team is working to address concerns with the FCB home jersey," a spokeswoman said.
"All product concerns are treated with the utmost importance and a solution is expected when all appropriate testing is completed."
Despite the problems with the shirt, Barcelona do not appear to have been unduly affected on the pitch so far this season.
The Spanish and European champions are currently unbeaten, and defeated Atletico Madrid 5-0 at the weekend, courtesy of a Leo Messi hat-trick.
