I know it's early, but I thought I'd get this ball rolling because the USA rugby team
announced their 2013/2014 jerseys, to debut against Ireland, and for supporters of teams supplied by Canterbury (Leinster, etc), it might be a signpost for this upcoming seasons' designs.
I really like their Home design. (I have their Rugby World Cup 2011 kit, but it was essentially a plain default Canterbury jersey, I like how the USA are getting more attentive designs)
