I bought the luggage bag for a einwöche cycling in summer. It offers enough room for standard equipment. When it rains, but you have to pick them up to dry land. When I came in heavy rain, the interior of the bag was angenäßt after about 20 minutes. So if you expect more rain resistance, should take up a higher-quality product. The shims made of plastic you have to trim with scissors to fit in the provided holders.
