Blackburn calls this their Local Pannier, intending it for day trips not touring or bike camping. It is designed to be used for riding to work or school.
A molded inner liner holds the panniers shape as compared to touring panniers which collapse when not filled.
And a top flap design is a better choice for getting in and out of the bag several times a day, compared to the roll top closures of touring bags.
The fabric is water-resistant coated nylon, includes a loop for attaching a light and has a bit of reflective print to help keep you visible.
Includes a shoulder strap for carrying.
