Combination of soft FKM rubber on the inside and a sturdy sailcloth cover on the top with silver, black or bronze buckle. 

FKM rubber (part of Fluoroelastomer) is a more advanced alternative to silicon or the usual rubber strap. This material offers better resistance to atmospheric influence, oil, acid or chemicals and high temperature, in addition to full water resistance. This makes them ideal for any water or sports related activity.

Equipped with quick release spring bars - no tools needed. 

Bronze - Please note that bronze will change its colour over time and develop a vintage patina within a few days of wearing it.
