Here is some helpful information about our BRD Kayak SKINS. We do not use the same material used for wraps which is 2-4 mil thick. Our BRD SKINS materiel is three to four times thicker than a traditional vinyl wrap. It is formulated specially for marine use in fresh or salt water. Easy to clean after being in dirty water and very durable. The total weight of our Kayak SKINS for most kayaks is about 2.5 pounds. Easy to install this air release backing and easy to remove when needed.
