An ultralight pack from Gregory means weight savings without the loss of practical features. Another top quality pack that looks great and performs even better with a super comfortable fit.

Gregory says:

Longer distances and winter temperatures require extra room. The Optic 58 gives you that additional capacity without compromising your ultralight priorities. Proper load management, moisture-wicking ventilation, and intelligent features keep you comfortable and mentally balanced from sea level to the High Sierra, because efficient trail travel involves more than a weight claim.

Gregory's Optic 58 Rucksack utilizes Gregory's new AeroSpan suspension system which is an ultralight version of their VaporSpan suspension. It delivers the same combination of 360-degree moisture-wicking ventilation and tensioned perimeter frame load management while paying obsessive attention to weight reduction. It also features FocusForm shoulder harness and hipbelts and LifeSpan foam to provide lightweight comfort that should outlast other weight-conscious cushioning materials.

The rucksack fits in a lot of features while still managing to keep the weight down. You even have the option of removing the lid and swapping it for the ultralight weather flap to go full on minimalist. The only small issue I had with this is that it can be a little fiddly to remove the lid and I would have preferred a simple clip instead of threading it through the buckle - yes it might have added a few extra grams but that's just my preference as I feel the more it gets used the more difficult it might become to remove and attach.

Overall it's a great pack for backpackers and hikers who don't want to carry loads any more than 16kg.

Gregory Optic 58 rucksack

The Gregory Optic 58 sack replaced my Nigor Zero-G pack that I'd only had for a year. The Nigor had four months use, and whilst the design in theory was utterly perfect for my needs, I was disappointed at it's tendency to self destruct. Eg. the inverted U-shaped back-stay penetrated the bottom of the sack, despite my attempts to alleviate this issue, and the hip belt/pockets internal plastic reinforcement panels, being un-chambered, pierced the pocket fabric. I really wanted to love this Nigor sack, but after only four months it was already on the way out with, in my opinion, these avoidable design oversights.
Ultralight Outdoor Gear listened carefully to my concerns, and I am now the happy owner of the Gregory Optic 58 sack. This is my second Gregory pack (the first being a thirteen year old Z55). Gregory's reputation for comfortable sacks is in evidence with the Optic 58. I'm currently in the Pyrenees on the HRP, and despite carrying a weeks worth of food at a time, the Optic is always very stable, and very comfortable.
I place an emphasis on comfort over weight. I would not describe the Optic as ultralight, but as a lightweight, fully featured sack. I retain the removable lid which has generous internal and external pockets, and ditch the rain cover (using MLD DCF drybags instead). The basewieght of 7kg plus food, 1L of water and fuel carries very well.
The aesthetic design is a bit glitzy for me - I prefer an understated look in the hills, but does that really matter? Not really when it carries so comfortably. I've always thought air panels/suspended back systems as rather gimmicky - you'll still get a sweaty back with no sack at all, but the through draft is very welcome. The hipbelt pockets seemed quite small non first inspection, but in fact are more than adequate for a days worth of trail mix. I'm concerned about durability of mesh front pockets, preferring solid zippable pockets that withstand airport baggage control, train/bus luggage compartment bashing better. But for now, the Gregory 58 is excellent and I can recommend it wholeheartedly.
