I really like them. I use two different kinds of day bags. One type is made of canvas. These are not very expensive and very durable. The other type I use are the silver-colored, insulated, polyethylene coated nylon tarp material. The former are like a big sock and difficult to remove from a 9ft or longer board. The latter have zippered sides that make it easy to remove or emplace any length board. The price range for these bags is $40 to $80 US. I boought a 7ft 8in canvas bag and a 9 ft canvas bag new for about $40 US. for about I bought two 9ft nylon bags used, but in excellant condition. One was $45 and the other was $52US. In addition to protecting the boards and making them much easier to handle, they protect everything else from the wax that is on them. If you decide to get a board bag, be sure to remove it before advancing into the water.
