Big enough for an overnight, light enough for a day hike, the Zulu 45 uses a dynamic FreeFloat suspension, providing comfort in all environments. With an athletic look, full adjustability, and refined materials, we straddled the line between a daypack and overnighter.

AeroSpan ventilated suspension with moisture wicking mesh

Speed Clip hydration hanger attachment system

Dual layer bottom panel for added durability

Adjustable torso provides 3.5"" of adjustment, allowing for a custom fit without compromising support.
Gregory's patented FreeFloat dynamic hipbelt links the hipbelt to the frame with a panel designed to move and flex with your body.
3D hipbelt design conforms to the shape of your body, seamlessly providing the padding and support needed to carry heavy loads.
Full-length tensioned mesh creates space between your back and the pack to allow for heat to escape and air to flow freely to cool you down.
Designed around the architectural principles of tension and compression, the perimeter frame provides stable, yet flexible support to comfortably carry the load on your back.
Extra large hipbelt pockets provide secure, easy to access to the essentials you want at your beck and call.
Constructed from Lifespan foam to provide a generations worth of comfort, the shoulder harnesses are perforated to maximize airflow and comfort on the trail.
Main U-Zip opening for open access to the main compartment.
Hydration sleeve with SpeedClip hydration hanger, compatible with Gregory's 3D Hydro reservoirs (reservoir not included).
Top zippered pocket with reflective attachment points, key clip, and internal zippered security pocket.
Dual side stretch mesh pockets with pass-through for over or under compression.
Front stretch mesh pocket with durable fabric front panel and secure buckle closure.
Adjustable attachment loop and upper shock lock for trekking poles or an ice axe.
Custom ComfortGrip molded zipper pulls.
