1941 Royal Air Force Sweater – 100% Merino – Pike Brothers

The 1941 Royal Air Force Sweater from Pike Brothers is a classic military-inspired wool jumper based on original garments worn by British fighter pilots during World War II. Historical photographs show how such sweaters were worn under flight jackets in the cockpit, providing warmth without restricting movement.

The model recreates the cut and details from the period with a high degree of historical accuracy. The result is a simple, functional sweater with clear roots in military workwear.

The sweater is knitted from 100% merino wool. Merino wool is known for its ability to regulate temperature, wick away moisture, and feel softer against the skin than traditional wool. The material provides good warmth without the garment feeling heavy.

The fit is relatively slim, inspired by the close-fitting garments pilots wore under leather jackets and flight suits. The silhouette means the sweater works well both on its own and as a layer under jackets.

The sweater is produced in Portugal and features a period-correct woven label that emphasizes its 1940s inspiration.

About the material

This sweater is made from 100% merino wool, a fine-fibred type of wool from Merino sheep. The fibres are thinner than traditional wool, resulting in a softer and more flexible knit.

Merino wool has natural temperature-regulating properties. The fibres retain warmth in cold weather while wicking away moisture when the body gets warm. This is one reason why merino wool has long been used in both military gear and technical outdoor clothing.

The tight knit structure also provides good durability and helps the sweater maintain its shape over time.

The history behind the RAF sweater

During World War II, Royal Air Force pilots wore multiple layers of clothing under their flight jackets to stay warm in unheated cockpits. A tightly knitted wool sweater was one of the most practical garments because it provided warmth without restricting movement.

Such sweaters have since become a classic within military-inspired workwear and heritage clothing. The combination of functionality, simple construction, and durable materials still makes them popular among enthusiasts of classic workwear and vintage-inspired apparel.
