The Zpacks Women's Arc Zip Ultra 62L is a 62-litre pack built on a carbon-fibre Arc Frame, weighing 678 g — about 10.9 g per litre, light for a pack this large thanks to the carbon frame doing structural work that heavier aluminium stays would otherwise handle. The frame's arched design also holds the back panel away from your body for airflow, and back length is adjustable to fit the wearer.
Cut to a women's-specific fit, it adds a zippered front panel for reaching gear without unpacking the main compartment, plus a padded hip belt to carry the load on your hips rather than your shoulders. Zpacks rates it for thru-hiking and multi-day trekking, and the 62 L capacity suits longer trips needing more food and gear between resupply — for shorter or lighter trips, a smaller Zpacks pack in the same Arc Zip line would carry less weight for less bulk.
