Even just the name of this company makes me smile! These guys are Kiwi designers of kids clothing and my recent purchase for my son was the below tee.
Price wise they are pretty much on the ball as the quality you get out of this is great. Soft, yet strong and wearable for the kids. We gave it to 'Cheeks' for Christmas and he absolutely loved it .... not quite the reaction you usually get when giving your kids clothes for a present!!
I actually bought this off the net, but their website contains further details.
