Calfskin with contrasting interior and exterior textures using the grain side and the other slightly silvery side both facing outwards.
A vegetable tanned leather using bark and leaves which develops a beautiful patina, gentle on skin but sensitive to humidity so moisture could leave a contact colour residue which will subside over time.
Apply water and stain protector before wearing and after each clean, avoiding shoe polish. For regular cleaning, gently wipe using a soft dry lint free cloth or suede brush moving in direction of grain. If dampened allow to air-dry naturally away from direct heat.
