I am selling this item because I don't use it much, even though I purchased it here. It has some scratches and stains from normal use. This is an old model (late model, with adjustable shoulder strap) Tanker Helmet Bag. While the early model (with a non-adjustable strap) is occasionally seen, the late model is rare. This is a very popular model, so it's difficult to find. Size is L. (Height 51cm, Width 47cm) I believe it's from an old model.
