Purists will love the lightweight, dialled-back style of the Aerios, although its size definitely makes it more of a daypack than a racepack.
Made from incredibly light nylon, it’s prevented from collapsing in on itself by a firm back panel, which is noticeable when riding.
The pack's lightweight advantage does mean you pass up the benefits of multiple pockets to help you organise your gear.
While the small stretch side pouches are fine for food, you’ll need to carry your tools in the main compartment. There’s a small zipped secure pocket inside for keys and cash too.
The outer bungee is handy for stuffing jackets into and if you’re not running fully packed, it can act as a compression strap as well.
