Danuu designed these covers to be easy to use, simply by pulling them on. The covers can be used on both SUP and long surfboards. It can be a quick cover before putting your board in the back or on top of the truck or in the garage until your next go out. This cover is made of a durable denier that keeps the SUP deck pad in good condition and it also has a velcro fin slit and elastic trim that is backed by a rope tie to pull it tight, this board cover is the BEST! The Danuu Board Bro can fit boards up to 33″ wide and 12′ ft long`.
