This is the Sea to Summit Comfort Light S.I. sleeping mat. It is a lightweight and comfortable mat, ideal for outdoor activities such as camping and hiking. There are no noticeable scratches or stains, and it is in relatively clean condition. I bought it for tent camping, but it was only used twice by my child during family camping trips. It was used after bathing, so I don't think there are any strange odors or sweat stains. However, as you can see in the photos, there are some unclear stains. No pets, non-smoking environment. When stored, it was not folded but kept in its natural inflated state, so I believe there is very little deterioration from folding. There are no air leaks. All accessories are included. I am selling it because I don't do tent camping anymore, and it is a bit too narrow for me. I bought it for its lightness and comfort, so I think it's good for tent camping.
