I was just on my way here to say that, David!
Where I live, it's impossible to find any tshirt for less than €5, except from Decathlon. They do organic for €5 and non-organic for a bit less, including in a nice muted khaki green colour. I'm usually a complete tight-wad with my money but I do think it's worth encouraging Decathlon by forking out the extra for their organic tees. The weave is a bit lighter on their organic range, but in this summer heat I consider that definite plus!
