1 • Main zipper

This is a YKK #8 zipper, which is more heavy duty than a standard bag zipper without being overkill.

2 • Shoulder strap

The shoulder strap is 5cm wide (the same as a car seatbelt) and fully adjustable. Like all the larger bags they can be clipped on and off so you can choose your own colour.

3 • Internal dimensions

The internal dimensions are a little smaller due to the canvas lining.
The largest object that would fit is 35cm tall x 30cm wide deep (includes a 13" laptop and/or A4 paper and magazines).

4 • External document pocket

This open-topped pocket is great for magazines, or other larger objects that requires easy access. 
It's deep enough to securely A4 papers, an iPad and/or 

5 • Reinforced base & bike loop

The printed feature fabric panel is reinforced along the bottom edge to protect from wear and allow the pocket to expand as required. 

Another recent addition is a discrete recessed loop on the outside corner. This makes it easy to add a stabiliser strap that prevents the bag moving while cycling etc. These straps are available in the accessories section and can be easy added to any bag with this loop.
