I had to have a padded bag to fly with my board. This one on sale was only $75, and they recommended size 156 for a 149 ladies board. It fits exactly as it should, with room for my boots. I could fit another deck if I wanted to. The bag also has a roomy external pocket. The shoulder strap is padded.
It is lined with a sort of metallic material, and it seems very durable and sturdy. I have not yet flown with it, but the seams look strong and the padding seems ample.
I am glad I chose this bag.
