"Cotton production uses chemical insecticides on a vast scale. Almost a
quarter of all pesticides used gloabally are used to grow cotton.So, cotton on: buy organic." - Leigh Chadwick, Seasalt Organic Cotton Clothing
And, frankly, when you can get such good organic cotton clobber as the £25 Howies tee on the left, why would you want stuff filled with chemicals? Other good organic tee companies to check: Indigo Clothing (for bulk, bespoke orders), Glo4Life (for superb graphic designs) and Hug (for kids).
