What kind of backpack is this
Gregory has launched a brand new series for men and women under the names Optic and Octal, respectively, each with two packs’ sizes. The Optic packs are described in my Optic 48 and Optic 58 reviews. This Octal 45 is the smaller pack from the women’s series which also includes the Octal 55.
This is an ultra lightweight series. I know that there exist lighter packs on the market, but typically such low weight is on the account of some essential features. In the case of the Optic and Octal series, very few features are missing, this is what puts them above some other ultra-lightweight packs. This pack has just enough features for all you need, and most importantly its suspension is perfect.
The pack is a top loading type, and the lid is removable. This is done on purpose so that you can reduce the weight even more. For such a lidless use, they have included a flapjack which you attach to close the pack. With the flapjack, it looks shorter, see the picture below.
The main compartment is with the top access only, and you have a sleeve there for a water bladder. The port for the hose is in the middle and you route it over any shoulder strap.
Who is it for
When you see the features below, you will realize that these are excellent tools for backpackers. The reason is that they are so lightweight, yet built to carry the load comfortably. You have strong and comfortable suspension which works well for the weight these packs are designed for.
This pack is for women, and it is built in three sizes. There is no harness adjustment here, therefore choose your torso size carefully.
In view of its removable lid and the dual V-shaped compression straps on the sides, this pack can be used even as a daypack. But it is perfect for weekend hiking and backpacking tours.
Overview of features
They have what they call Aerospan system here. It is based on a 7001 aluminum frame which runs around the perimeter and ends up in the lumbar zone where it transfers the weight. This is a great design so that you have reduced stress on shoulders. A good pack is supposed to carry the weight mainly on the hip belt; up to 70-80% of the weight should go there so that you can breathe freely.
You also have a horizontal bar introduced to prevent barrelling. The frame is rigid but still flexible enough to follow your movement.
There is a tensioned mesh between the body and the pack, so the pack is completely separated for a free air flow. I have several packs of this type, and have been using them for the past 15 years and I know that this is the best way to increase ventilation. But do not listen to those who are telling you that you will not sweat; you will, but this is still the best design.
The hip belt and shoulder straps are with a truly great padding covered by a 3D breathable mesh, the padding goes around the edges and there are no seams to create hot spots. They use different padding and mesh in different zones, dependent on the pressure expected in such areas.
The lumbar zone is usual for Gregory, and this means massive, see below. So this will give you all support and comfort you need. The adjustable sternum strap is sliding type so you can set it at any position you want.
The front hip belt straps are dual from each side, see the picture below. This is again a very nice design because of the hugging effect around your hip bones. You do not have this in the case of a single strap design.
To start from the lid where you have two pockets, one with the access from outside and the other with the zippered entrance underneath the lid. The latter contains the rain cover and the mentioned flapjack.
The side mesh pocket and the front large pocket are of the same material and when empty they stick to the pack’s body. But they can take lots of stuff. The side pockets are with dual access, from the top and from the side (see the picture below), so that you can easily grab your water bottle. The front pocket is with a buckle which you will use to secure the stuff in it.
Dual zippered pockets are available also on the hip belt. So you have 7 pockets in total.
The straps are narrow, built that way to shed the weight, but they are strong and useful. You have it on the bottom for a sleeping pad, and also on the sides.
These dual side straps span all the way from the bottom to the top because of their V-shape, so they cover all the area and you can cinch the pack to a very small volume, but you can also fix anything there and carry attached to the pack. Note that the lower straps are with inside-out feature, so you can use them through the pockets or across the pockets, dependent on the purpose.
There are trekking poles loops and bungees higher on the front. They also added the QuickStow bungee cord on the left shoulder strap for glasses.

Good and less good features & rating
Here is my short summary:
- Great weight.
- The weight can be stripped.
- Very high volume/weight ratio.
- Great ventilation.
- Excellent suspension system and padding.
- Quality materials and workmanship.
- Bonus rain cover.
- No bottom compartment.
- Not adjustable harness.
- A bit expensive.
The price & rating
As of the moment of writing this text, the Amazon price for the Octal 45 pack is $190. It is expensive, but it includes the rain cover which would cost around $35 if ordered separately. From this perspective, the price looks more acceptable. See how I rate this pack:

Gregory Octal packs vs Osprey Eja packs
There is yet another ultra-lightweight series for women launched in 2018 by Osprey, the Eja series. So here I compare the two series, so see what I think:

Gregory Octal Packs
Osprey Eja Packs
You can see more about the Osprey’s packs in my texts about Eja 38 and Eja 58. The Eja packs are great but the hip belt design in the Octal packs is better. The same holds for the packs for men, the Gregory Optic packs and new Exos 2018. In my view, this time Gregory is better; see more in my separate text.
