DLO is now shipping their Action Jacket for the iPod nano. (With a name like that, I can't help but think of that movie classic Action Jackson with Carl Weathers). ;)
The Action Jacket is a protective casing for your iPod that includes a sweat resistant Neoprene case, 180° rotating belt clip and an adjustable armband. Seeing the Action Jacket in bicep pumping action is putting me in the mood to go to the gym for the first time in 4 months!
