Ok, not great..
Size is ok for 14" laptop or a 12" iPad Pro, where it is severely let down as an action man, enter Embassies via Rappelling is that the padded area on the shoulder strap is slippery as anything, rest it on your shoulder of a high-vis, and off it slips...nothing to grip on the underneath at all. Average at best, went from a £20 Amazon job to this and if I hadn't cut the label off i'd have returned it.
