Thule Shield pannier 22L is an urban bike bag perfect for bike commutes.

City-dwellers on their daily commute will appreciate the padded laptop sleeve for a 16" MacBook® or 15.6" PC, and the additional pocket for a 11" tablet. Installing the pannier on your 8-16mm bike rack is easy, and once installed, attaching and detaching the bike pannier takes mere seconds. The bike light attachment loops and reflective elements keep you visible when you're cycling at night. These panniers also have a certified rating of IPX4 on the internationally recognized IP waterproof scale, which means they are highly water-resistant in heavy rain and will keep your items dry.
