Nomatic Navigator Sling 6L

The Navigator Sling 6L is the commuter size, 13.5 by 9 by 4 inches and 6 litres, organised more carefully than a bag this size usually is. The main compartment has four pockets including mesh, zip and an RFID-safe pocket for cards, with a cord pass-through so a battery in one pocket can charge a phone in another. The back pocket takes an 11 inch iPad Pro or a slim handheld.

The strap carries its own card slot for a transit pass, and a tuck-away stabiliser strap steadies the bag when you move. A hidden external pocket holds a key leash; the water bottle pocket folds away when empty so the profile stays flat. Water-resistant tamper-proof zips and reflective bars, on a molded EVA back panel. Strap runs 30 to 60 inches; the sling weighs 1.3 lbs.
