[1] The first Harrington-style jackets were claimed to be made in the 1930s by the British clothing company, Baracuta.
[3] The British company Grenfell, previously known as Haythornthwaite and Sons, also claims to have invented an identical jacket around the same time based on their golf jackets,[1] which is also still in production using their own signature cotton.
The Harrington from either original source is based on lightweight, roomy jackets worn to play golf hence the G in the G4 or G9 naming convention for Baracuta.
Baracuta originally manufactured their jacket in Manchester whereas Grenfell were based in Burnley then London.
