The ultralight Gregory Women's Octal 45L Backpack is designed to maximize comfort and enjoyment on backpacking trips. With the weight savings and reduced stress on your body, you can hike further and faster, but go ahead and take it at your own pace. An internal aluminum frame supports heavier loads and efficiently transfers weight to the hips while the women's specific harness and padded hipbelt enhance comfort. An internal sleeve with hose port holds onto your bladder to deliver hands-free hydration, but there are also side stretch mesh pockets that are angled forward so you can easily grab a water bottle on the move. Now let's talk about back sweat. Nobody likes it. This pack features an Aerospan suspension with a well-ventilated backpanel that wicks moisture and promotes airflow against your back.

Lightweight and very comfortable!This pack is just what I hoped it would be. Lightweight and comfortable for multi days in the back country. I have several Gregory packs and for good reason. Lots of features without the added weight. All my gear fits just right without going to my heavier other brand pack. Nice to shave those ounces/pounds down without giving up the comfort of carrying the load. Nice to use either the "brain" or light weight top cover, depending on amount of gear.
The outside pockets are plenty big for stowing tent gear and water bottles, if you choose not to use the inner pouch for a hydration system. The shoulder sunglass clip is very handy.

Great Lightweight Pack[This review was collected as part of a promotion.] I just recently purchased this pack after doing a TON of research on packs and reading endless reviews. I bought this pack and the Osprey Eja. While the Osprey pack was also lightweight and comparable in capacity, the Octal beat it on comfort with much more padding on the hip belt and the bonus hip pockets. I have only used it for hikes up to 10 miles...but I tested the Eja the same way and it immediately did not feel good on the waist and hips. I also own a 60 liter Gregory Jade that is like 7 years old and it is still in great condition. The Octal is just lighter and what I will use for our 2020 PCT Thru Hike.

Practically love it.I love that this pack is so light weight and still has most of the features of the heavier backpacks. I find if I pack too much weight the pack will not be as comfortable and tends to pull back, no matter how the load lifting straps are adjusted. Another feature that is a con for me is the loops on the shoulder straps which can be used for attaching items to are made of a stretchy elastic. Anything that has weight, such as my Garmin or cell phone pouch, when attached to these loops stretches out the elastic and makes it difficult to keeps the attached item in place.

Comfortable, durable and all around great pack!Extremely comfortable and has made it possible for me to hike long distances 20+ miles in the rugged high desert carrying 25-30lbs with minimal discomfort afterward. As an Army Veteran I have a few aches and pains, but this pack fits perfectly and the wide shoulder space does not aggravate my neck. The pack is very durable, spacious and has a number of useful features. In 90-100+ degrees this pack helps keep the heat from building on my back. My only wish would be for more sinch straps across the pack, it looks bulky. I would buy this pack again and it's why I came back to Gregory for a Juno 30 Hydration pack.

Great lightweight pack, would buy again in a heartbeat!Replaced my Gregory Sage 55 with this pack while they hiking the Appalachian Trail. I love this pack!! So lightweight and easy! I use a hydration bladder with my inline water filter, and it fits right in the stretchy outside pouch. The only downfall I see is that my Sage had nicer bottom straps that I could attach my bivy to, whereas the Octal has a slightly different strap system on the bottom that isn't as easy to use. I utilize it mainly for a z-lite pad that I can just sort of cram into place.

Great Lightweight BackpackAbsolutely love this backpack for trips up to about a week. Lightweight, lots of pockets, seems durable for a light pack. The only issue I have with it is I'm carrying more weight on my shoulders because the torso length is a little short for me. I tighten the belt well around my hips, but the shoulder pads still rest too much at the top. I'm only 5'8", but do have a long torso. The length wasn't listed in the specs, so didn't know. I probably should have gotten the mens. The hipbelt fits well, big pockets. It's much bigger and more comfy then the other well-known brand that made all of its hipbelts too small (even for an average person like me). Still will use this pack, not sure why it's not sold more at big stores, it's awesome!

Decent pack but not perfect. I don’t backpack much and this is the first backpacking pack I’ve owned, so take with a grain of salt— I don’t have anything to compare it to. I just used it to hike in to base camp for a big mountain climb. It fit everything well, and I love the stretchy mesh on the outside. However, after 16 miles with it fully loaded, I have an epic bruise/wound on my right shoulder. When I loosened the shoulder straps and tried to carry the weight on my hips, my mid back would hurt. It’s possible I just haven’t figured out the straps yet, but definitely cannot quite give this pack a 5/5.

Overall after modification good packMy 4th gregory pack, i am xs so choices are limited, but on this pack shoulder straps tooo long, as a result the pack to frame adjustment then was zero which made uncomfortable had to hold pack up from behind, i sewed them shorter, not optimal, the rain cover is only good if you use pack as day pack, totally too smal on even overnighter, had to buy another, which of course does not fit as well, also body to shoulder strap distance is unusually large so had to modify by adding foam, what happened to gregory xs small fit??? Pack fits like a small size small, Disappointed Good pack, but you need to buy a rain cover, good if you can sew or it fits you Berg lake trail, mt robson prov park

Gregory Women's Packs
Gregory backpacking packs are available in a size range. Please check the PRODUCT FEATURES and / or SPECIFICATIONS for the torso range measurements of each size of a pack. The steps below are a guide for measuring your torso size.
The hipbelts on Gregory backpacking packs are adjustable to fit a range of sizes. A simple rule of thumb is that the ideal distance between the ends of the hipbelt pads after tightening should be 3 to 5 inches. However, the most important criteria are that the hipbelt wraps clear over the side of your body and that it rests 1 inch above your iliac crest. This allows proper load transfer to your skeletal structure, which maximizes comfort and minimizes energy expenditure.
HOW to MEASURE TORSO SIZE 1. Put your chin to your chest and feel for the big bone protruding on your neck at the top of your spine. That's the C7 vertebra.
2. Feel your hip bone, the top part of this is your iliac crest. Find the spot on your back that is level with the top of this crest.
3. Have someone measure the distance between these two points, following the contours of your spine.
