Weighing less than 2.5 pounds but still providing load-hauling support and organizational features, the innovative Gregory Octal 45 Women's internal frame backpack is ideal for ounce-counting female hikers and backpackers.

Addressing the different wants and needs of female hikers, Gregory's Women's backpacks cater to the woman on the go. Designed and tested by women, these packs incorporate shoulder harnesses contoured to fit the female figure and hipbelt panels built to adjust to fit women's hip angles. Reflecting the difference in male and female ergonomics, these packs also employ narrower backpanels.

The pack's suspension system utilizes a perimeter frame constructed of ultra-lightweight 7001 aluminum and includes anti-barreling support to ensure that weight is balanced and stabilized. Weight is transferred to the load-bearing lumbar support to minimize fatigue on your shoulders and back. A ventilated backpanel and dual-density padding in the contoured harness and hipbelt combine to increase comfort, fit, and breathability. Load lifter straps and an adjustable sternum strap further enhance fit and ensure stability. To ensure a customized fit, the pack is available in Xsmall (best fits 14"-16" torso lengths), Small (16"-18"), and Medium (18"-20") size options.

The top-loading pack offers more than 2500 cubic inches of storage capacity. A protective top lid includes internal storage but can also be removed entirely when the additional storage isn't needed or you simply want to travel lighter. Even with the lid removed, a small, buckled flap protects the interior of the packbag. A large front stretch pocket enables you to keep discarded layers or other gear close at hand. Side compression straps allow you to cinch down the packbag to keep the contents of the pack stabilized and also double as external lash points.

Other features include large side stretch water bottle pockets, zippered hipbelt pockets, trekking pole attachments, a front harness quick-stow feature for sunglasses, and an included raincover. An integrated sleeve and exit port make the pack hydration compatible (hydration system sold separately).

The Gregory Octal 45 Women's internal frame backpack is available in your choice of size and color options.

Bought this backpack for my wife. Worked very well. She likes it.
Reviewed by Min Z. - August 30, 2018

Likes: lightweight and good fit

Dislikes: none

Great backpack.
Reviewed by Susan S. - April 2, 2018

Likes: Lightweight but still has great features like hip belt pockets and removable lid. Everyone is different, but this pack fits me great.

Dislikes: Haven't found any dislikes. Because it's lightweight I found how I pack my gear is more important. I took it for a test run and strapped a 5 lb tent (not my normal backpacking tent) on the bottom. The weigh of the tent pulled the pack away from my upper back and put strain on my chest and shoulders.
