rear bag

fits on carrier quite easily and seems secure. plenty of room for the bits and pieces I need and the extra pockets make stuff easily accessible. could do with a custom fitting for rear light, clipping on the carry handle lets the light hang down. a good piece of kit and value for money.

Rear rack bag

Grand,bag of good quality ,one small problem base poorly finished to improve a separate base should be fitted to reinforced bottom of bag this should be removable to allow cleaning.Sorry only 3stars due to base.Also late delivery.

Top-quality bike bag

Fitted to my rear pannier, looks great, sturdy, well-designed, just the right capacity - holds my first aid kit, bike tool, tyre levers, pump, spare inner tube, mobile phone, notebook and pen, face masks...still room for more. Rear light fits on well. Highly recommended. Don't hesitate - buy one!
