I saw this on the Mini Simmons website. If I ever get to travel again, it looks like it would work pretty well. I have a smaller one from @midnight, but I would need a bigger one for my big board. If you look at the video, it looks pretty good. I don't know, if they will make a smaller one. https://www.wavetribe.com/collections/surfboard-travel-bag
They also have a day bag that is cheaper.
Among my many board bags is the Mini Simmons Day Bag. Well built and has many of the features one would expect in a board bag. What really separates from being a true "travel bag" is that the Day Bag is basically a rear entry bag rather than a full entry bag which doesn't provide as much flexibility for travel padding and packing, not to mention no internal straps to keep the board (and other items) from moving around. But in a pinch the Day Bag can fill-in as a travel bag. What I especially like about the current travel bag are the extra padding in the nose and tail.
Let me know if you end up wanting to order a WaveTribe bag. Also, they often have good sales around Thanksgiving for the Christmas season, usually only lasting a couple of days.
