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.
