Levi's new FLU sports inspired collection is causing something of a stir. Denim, a material not traditionally associated with sportswear has been engineered to withstand extreme movement and stretch a necessary characteristic for us street footballers who want to kick a ball in jeans. The Levi FLUÂ High Performance Stretch Jeans are truly innovative and a credit to the company. The Levi FLU Tee consists of three layers: dry layer, water absorption layer and the diffused layer, "Triple DRY" for kicking and keeping dry. The World Cup is clearly the catalyst for the Levi's FLU collection and compliments the Paul Smith World Cup football, wallet and cufflinks.
