Theo
Green Felt Hat

Theo - a bold winter style in rich wool felt.

Defined by its wide flat brim and classic teardrop crown, Theo is a striking seasonal shape crafted in wool felt. The structured shape offers a refined balance of elegance and edge, making it a standout piece for the colder months.

In a deep, sophisticated green and finished with a narrow tonal band, Theo brings understated drama and elegance to cooler days. A unisex piece designed for crisp air and layered looks, it’s a refined cold-weather companion with a bold silhouette.

Care

Steam from a household kettle and a hard bristle hat brush will help remove dust and dirt. Brush the hat using short strokes, following the natural direction of the fibre.

Wet hats should be dried using a clean, absorbent cloth or sponge. Do not place a felt hat on a radiator as the heat will shrink the fibres and cause your hat to decrease in size.

Felt hats are best stored in a hat box, away from direct sunlight.

Materials

The Theo is crafted from wool felt, is unlined and finished with a fine, narrow grosgrain band for a refined look.
