I bought this about 5 years ago because I wanted to try SUP, but I haven't had the opportunity to do marine sports since then due to pregnancy, etc. Therefore, I have been storing it folded up. As you can see in the photos, there are creases. There is no noticeable deterioration. Brand new, unused! The sizes are different for the top and bottom, so please check the photos m(_ _)m I will fold it up and ship it.
