Rubber B strap Alligator SwimSkin for 21mm.
Our KronoKeeper "Marius" strap is made from FKM rubber which is a man-made material that is soft to the touch but extremely dense and made to withstand very harsh conditions, such as extreme temperatures, humidity and chemicals etc. FKM rubber is commonly used in the aerospace and nautical industry. It is not prone to dust adhesion and is fully waterproof. The strap features a genuine nylon cordura resistant to tears, scuffs and abrasions on the outside and special moulded channels on the underside to allow air to circulate, moisture to drain away and makes the strap highly flexible and very comfortable to wear.
