1. Try to keep out of rain where possible.
If it should get wet, pat dry carefully and allow to dry naturally.
2. Brush your hat with a soft haired brush regularly.
3. If it should get dirty wipe gently with a damp cloth.
4. If the hat loses shape it can be revived with steam from the kettle.
Place the part that needs re-shaping near steam from the kettle, allow to soften slightly and reshape.
Leave to cool down and dry.
BE CAREFUL NOT TO BURN YOURSELF!
