The innovative Gregory Optic 58 internal frame backpack tips the scales at just over 2.5 pounds but comes equipped with a feature set and load-hauling capability that most packs that weight simply cannot offer.
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 Small (best fits 16"-18" torso lengths), Medium (18"-20"), and Large (20"-22") size options.
The top-loading pack offers more than 3300 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).

Real Customer Reviews
- Great Lightweight Pack with Nice Feature Set
Likes: I like the AeroSpan suspension. The frame transfers the load to the hipbelt while keeping the pack away from my back for better ventilation. The shoulder straps and hipbelt are well padded and the materials also help with ventilation. I also like the dual access side packets and large stretch front pocket. I like that you can remove the top lid and use the included lightweight flap instead of the lid. The included rain cover is nice addition.
Dislikes: I wish the top lid had longer rear straps so it could be raised to accommodate larger loads. I wish the shoulder straps had daisy chain so you could attach accessories to them.
