Magnets, straps or a ring — and what your tank is made of · review
A 20-litre modular rear bag — the maker describes it as a pannier, saddlebag and tail bag — measuring 26 × 18 × 59 cm at 1050 g, with a removable waterproof inner bag.
The bottom line Three sizes published with dimensions and weights, and a removable waterproof liner. It is a rear bag in a tank-bag family, and this page says so.
The listing names it as a pannier, saddlebag, rack bag and rear-wheel bag. It is in this family because the German shelf sells tank and tail bags under overlapping keywords, and at 59 cm long it is shaped for a rack.
Three sizes, each with dimensions and weight: 10 L at 23 × 10.5 × 46.5 cm and 700 g; 20 L at 26 × 18 × 59 cm and 1050 g; 30 L at 30 × 20 × 65 cm and 1150 g. Polyester. A removable zipped waterproof inner bag and a waterproof zip cap outside. Four buckles and four straps per bag, with shoulder straps at the two larger sizes.
Buckles and hooks let the bags join 2-in-1, 3-in-1 or 4-in-1. That means one mounting arrangement grows rather than being replaced, which is a real argument for a soft system over hard cases.
Waterproofing a bag means trusting its zips, its seams and its fabric together. A removable liner is one sealed bag inside another, replaceable on its own and carryable into a hotel. It is the answer that survives the outer bag wearing out.

The maker names it as a pannier, saddlebag, rack bag and rear-wheel bag. It publishes no magnets and no tank mounting, and at 59 cm long it is shaped for a rack rather than a tank.
A liner can be lifted out and carried, replaced when it fails, and trusted independently of the zips and seams of the bag around it.
Carrying luggage on a rack or over a pillion seat, in a bag that can be split up.
