The innovative Gregory Octal 55 Women's internal frame backpack tips the scales at just 2.5 pounds but comes equipped with a feature set and load-hauling capability that most packs that weight simply cannot offer.

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 3100 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 55 Women's internal frame backpack is available in your choice of size and color options.

Should straps could be better
Reviewed by Amanda C. - January 18, 2019

Likes: I have a problem finding packs bc I have lumbar lordosis and a anterior pelvic tilt. So packs tend to dig into my lumbar rather than sit against it. This pack is great for my lower back. I absolutely love everything about this pack except the shoulder straps. I love how minimal it is. I don't have to remember what pocket or zipper something is in. Plus I love the blue/indigo color!

Dislikes: Shoulder straps aren't comfortable. It doesn't hold the top part of the pack secure and the top wobbles a lot. I've tried several packs and I guess I have to sacrifice shoulder comfort for lower back comfort.

Love this pack
Reviewed by Susan S. - November 30, 2018

Likes: Light weight but still has all the features I want. The hip belt pockets sold me on this pack vs the Osprey Eja. I used it on a 4 day hike, carrying about 28 lbs & it remained comfortable the entire hike.

Dislikes: I'm a little concerned about the durability, but Gregory's great reputation puts me at ease.

xsmall too large :(

Likes: lightweight
capacity & features

Dislikes: shoulder straps too high up on my shoulders, couldn't adjust to get them low enough, foam on straps rough & felt like they would easily chafe- had to return.

Lightweight and seems pretty sturdy
Reviewed by Julie C. - April 29, 2018

Likes: hip belt, side pockets nice and big and accessible from top and sides. Packed it with all my gear except clothes, food and water just to see. Haven't really used yet. It held a bear canister and my gear just fine. Can't wait to try it out, not until June.

Dislikes: Nothing yet.

Ultralight Octal 55 a great pack
Reviewed by Shelly D. - April 26, 2018

Likes: Designed specifically for women. Lots of space. Love the hip pockets and extra straps & loops for storing gear. The hip belt & lumber support are very comfortable. This one is a winner!

Dislikes: None
