Alpinestars Tech Aero £139.99

Tested by Dan Sutherland, 2000 miles, one month

This has been my goto backpack, used for commuting and weekend riding. With easily adjusted arm, kidney and chest straps, the bag feels secure on my back at any speed and thanks to a low-profile aerodynamic design, remains relatively free of buffeting. The bag is also expandable from 16 to 26 litres with a single zip. I tend to leave it on its largest setting to accommodate daily essentials like my lunch bag and a clear visor, as I find the design makes it hard to accommodate anything that isn’t either flat or squishable in its 16-litre form. A rain cover tucks away in a pouch at the bottom of the rucksack.
