Nomatic Navigator RS Pack 15L

The Navigator RS Pack 15L is the light one: 2.4 lbs, 15 litres, expanding to 21 when the day runs long. The shell is 420D nylon ripstop with a water-resistant carbonate coating, which is where the weight saving comes from without giving up weather protection.

It holds a 16 inch laptop plus a tablet in a 15 by 10.25 inch compartment, and six internal pockets, mesh, stretch and zippered, keep the rest sorted. A hidden water bottle pocket takes bottles up to 3.25 inches across, a fleece-lined front pocket protects sunglasses and a phone, and there is a luggage handle pass-through for travel days. Tamper-resistant zippers, an EVA-formed foam back panel and an adjustable sternum strap finish it.
