The most technical bag on test, the Osprey Momentum (£80) is stuffed full of thoughtful touches, handy pockets and useful features.

The headline detail is the venting system on the back of the bag. Foam ridges have been covered by a mesh panel to ensure air circulates and that dreaded sweaty back problem is avoided. While I didn’t test this in the heat of summer, it certainly kept me dry with a full load.

The details that really stood out to me though are the ergonomic zip pulls, perfectly sized pockets, and the fact that every strap, zip and toggle is exactly to hand, just where you want it.

The Osprey Momentum is very comfy to ride with, it sits neatly and securely on your back, held in place by a chest strap and a waist strap. A 15” laptop sits inside a separate back compartment, and there’s also a zipped compartment for a tablet. The Momentum is topped off with a handy helmet attachment and a stowable high-visibility rain cover, complete with loop to attach a rear light to. For a regular commuter, you’ll not want much more – every possible need has been thought of.
