The Oslo is a luxurious upgrade of the traditional flat cap. Made from sumptuous wool tweed it has internal ear flaps that are lined with soft fleece and can be worn down in colder weather. The cap is durable and has a flexible texture to ensure a perfect fit.
With a sleek silhouette, this cap is available in a choice of dark grey or a light green/brown herringbone weave, making it an ideal piece for the man about town as well as for country-style living.
The cap is finished with a satin lining and cotton sweatband and carries our treasured label.
Due to the inner ear flaps, we recommend you choose one size larger.
