Nomatic Navigator Collapsible Sling 3L

The Navigator Collapsible Sling 3L folds into a fully zipped case with a hanging loop and stores inside any Nomatic travel bag, then comes out at the destination as a 3 litre sling for wallet, phone, keys and a camera. Collapsed it is 2.5 by 4.5 by 5 inches; expanded, 3.5 by 9.5 by 5.

Adjustable straps compress the load so it rides tight against the body rather than swinging, and the EVA foam back panel keeps it comfortable over a shirt. Four internal mesh pockets do the organising, all inside durable water-resistant material. It weighs 0.3 lbs.
