Zpacks Women's Arc Haul Ultra 60L Backpack

The Zpacks Women's Arc Haul Ultra 60L pairs a curved carbon fiber Arc Frame with a tensioned mesh back panel, a combination designed to hold the pack's fabric off your back for airflow while the frame transfers load to a padded, pocketed hip belt. Built from Ultra 100X UHMWPE fabric and fitted with load lifters, adjustable torso length, and a women's-specific cut, it weighs 611 g for 60 liters of total volume (47 l main compartment plus 13 l in pockets) — about 10 g per liter, and rated to carry loads up to 40 lbs (roughly 18 kg). That combination of full 60-liter capacity and a real load-bearing frame sets it apart from frameless ultralight packs: it suits longer trips, resupply-heavy thru-hikes, or hikers who haven't trimmed their base weight down to frameless territory yet. A top-lid main compartment, one front pocket, two side pockets and hydration compatibility round out the storage, though there's no integrated rain cover, so a pack liner or cover is still worth carrying in wet conditions.
