Of course, just to pre-empt the 'how much?' brigade, you can get cheaper Harringtons and we've featured them on this site until we're blue in the face. But for something a little different, check out this Fred Perry Harris Tweed Harrington.
Produced, no doubt, for when the temperatures plummet over autumn and winter, this Fred Perry Harris Tweed Harrington is (as you've probably guessed) made from authentic Harris Tweed and is fully lined for even more warmth.
Aside from that, it keeps the classic profile, adding in the Fred Perry logo, a Harris Tweed Label and a brass zip. It retails for £349.
