Durston Gear Wapta 30

The Durston Gear Wapta 30 is a frameless ultralight pack with a 30-liter main body that expands via its roll-top extension collar to a claimed 46 liters including pockets. It's built from ALUULA Graflyte V-98 UHMWPE composite fabric, which keeps total weight down to 520 g — a ratio of 57.7 liters per kilogram that puts it among the lighter frameless packs in its class. With no internal frame, the Wapta 30 relies on a contact-padded back panel and a padded, removable hip belt with pockets; a sternum strap is included, but load lifters are absent, which is typical for frameless designs that don't route load through a rigid frame to the shoulders. The pack carries one front and two side pockets and is hydration-compatible, though it has no integrated rain cover. It suits ultralight thru-hiking and demanding day trips where minimizing carried weight matters more than raw load capacity or comfort under heavy loads. The two-year warranty is a reasonable commitment for such a light fabric.
