Sea Island Cotton

Sunspel’s most luxurious garments are crafted from Sea Island cotton, the finest cotton in the world. It’s also the rarest and accounts for just 0.0004% of all the world’s cotton. Sea Island cotton has a longer staple (or fibre) and a finer texture than any other, making it unusually difficult to grow and spin. There is, however, no other cotton that has quite the same extraordinarily soft feel against the skin.
Our long history of working with this remarkable cotton dates back to the 19th century. Today we source our Sea Island cotton from a few small-scale farmers in the Caribbean, and work with specialist technicians in Switzerland to spin and knit our unique fabrics. Sunspel’s Sea Island cotton remains the last word in luxury for underwear, T-shirts, shirts, polo shirts and knitwear.
