The Papa Nui Sub Hunter Cap came about after a request to the Papa from Ernest Hemingway. The story goes that in 1943 Hemingway needed a cap perfectly suited for chasing U-Boats in the Gulf Stream. He contacted the Papa with his requirements and the Sub Hunter Cap was born. Naturally Ernest loved his Sub Hunter, so it has been perfectly reproduced to the Papa’s exacting standards.

The Sub Hunter is constructed from a rugged Khaki Herringbone Twill with a contrasting brown Canvas brim. As hard-wearing as it is handsome, the Sub Hunter Cap will age beautifully over time.

To find out more about how to measure your head to get the sizing of your cap perfect, see this detailed post about Papa Nui sizing. Need more information on how to fine tune the sizing of your Papa Nui cap? Our sizing page also contains information about how to stretch or shrink your cap.

Before attempting to stretch or shrink your cap, please see the Care section to see if this is possible with your model.


As with all Papa Nui caps, the Sub Hunter is a hard wearing piece and is ready for anything you can throw at it.

When necessary, we recommend machine washing your Sub Hunter cap on a cold cycle. Allow to dry naturally. If your Sub Hunter fits you perfectly, avoid tumble drying as this may result in slight shrinkage.
