    The traditional flat cap gets a luxurious upgrade in the form of the Oslo. 

    The cap comes with a complimentary canvas cap bag.

    To ensure that you choose the perfect hat size, use our easy measuring-tape technique to get it just right.

    1. USE a soft tape measure.

    2. PLACE it around your head, positioned mid-forehead and just above the ears.

    3. MEASURE in centimetres or inches.

    4. FIND your size on the hat size chart.
