Just a few months ago the boys of Big Bang were dressed up in rugby polo shirts endorsing clothing for Korea's apparel company BSX. Now, they're ditching the short sleeves with their latest endorsement for Korean sportswear manufacturing company FILA. Big Bang has been endorsing FILA since 2008 and now they're back to model for FILA's upcoming 2010 winter line. Looks like the guys had a lot of fun during the photo shoot, especially G-Dragon with the snowboard. Thanks to Ryel for the tip and sharing the photos, check them out below. [gallery]
