There is a reason this particular knit has a legendary reputation. Sunspel originally developed its unique warp-knit cotton mesh in the 1950s to keep up with Mediterranean heat, and it remains unmatched for keeping you cool. It is incredibly light, soft to the touch, and allows air to circulate freely. The slim silhouette sits close to the body without feeling restrictive, finished with a clean patch pocket on the chest and a classic two-button placket. This hazelwood tone is a softer, warmer alternative to standard beige, pairing naturally with washed denim or relaxed linen trousers. Made in Portugal from fully traceable Californian Supima cotton, it is built to hold its shape through years of wear and washing. It is the definition of understated British design that does not need to shout to get noticed.
