Sansdon T-shirts are made by hand in England using 100% Sea Island cotton: the rarest, softest and strongest cotton on earth. It makes up less than 0.001% of the global cotton supply. No other cotton comes close. Our Sea Island cotton is grown in the ideal climatic conditions of the Caribbean, harvested with great care, and traditionally processed. We make our T-shirts in one factory to one garment pattern. This is surprisingly rare. We seek absolute consistency, because if it's the best, it needs to stay the best.
