The bag is very large, I've been able to fit in a full winter suit when I expand the zipper. It also unzips from the magnetic bottom so you can use it as a bookbag. No issues with it scratching the tank. The rain cover keeps it dry even in heavy storms. If you want a really large bag, I recommend this.
