Knitted caps that cover the ears, either by means of separate flaps that may be tied under the chin, or by way or an extension around the back of the head, can be documented in Europe from the 14th through 16th centuries. They are ideal for layering under other headwear (team with a Tudor cap for a good look for older or clerical gentlemen) or wear alone (ideal for 'apprentices' and working men).  
 
An red dyed coif similar to my version with  a plain back like the brown one in the pictures was found at Basel where it had been clumsily made more fashionable by having its edges slashed, then lost by a worker on the cathedral only to re-appear centuries later.
 
There is quite a lot of variation possible in these caps, so pick the nearest approximations in the drop downs, but let me know if you want any other tweaks made to get the right look, shade, and size for you.
 
Pure wool, handknitted, heavily fulled. Other shades or sizes available on request. Made to order. The way our order book is currently working, we open the shop approximately once a quarter for new commissions and shut it again once we have as many orders as we think we can realistically make over the next three months or so. Please be aware that your order may fall anywhere into that timescale. We'll always aim to be as prompt as we can.
