If you are after a hard wearing single pannier, this Altura model is a great model for commuters. With high vis trim and a bright orange front, this pannier will help drivers see you on your way back from work.
The waterproof material is really effective and all the seams are tightly taped to make sure no water gets in, even in heavy rain. The 20 litre capacity is just about right for a change of clothes, a packed lunch and a few bike tools.
The pannier clips on and off a rack really easily and the solidly built mechanism looks like it will last. It also comes with a handy shoulder strap, so you can carry the pannier easily when it’s not attached to your bike rack.
