Purpose, function, maybe you have a valuable board and you keep it on your vehicle for long periods in the sun and your worried about dinging any part of your board, Then you maybe you shouldn’t get a Newf Surf (www.newfgsurfboardnet.com) bag and look for another companies board bag. Different bags for different reasons. Not me, I wanted to design a bag that was made for my adventures: easy carrying, good transport features and lightweight with padding in the critical areas (rails, nose and tail). All the customers that have bought our bags agree. The new Elite 360 series or our Original Design Surf/SUP/Race bag (sizes 5’4″-12’6″) in colors is that bag. Never buy a board bag again for that board you own with our lifetime warranty (A bag for life!). We will repair or replace your bag if unfixable with bag that is closest to what you originally purchased. We will make your old unfixable bag into some other functional item to live on and keeping it out of the landfill. We are a 1% for the Planet member and our bags are locally made.
