Gregory Optic 48 Internal Frame Backpack

Weighing just 2.5 pounds but still providing load-hauling support and organizational features, the innovative Gregory Optic 48 internal frame backpack is ideal for ounce-counting hikers and backpackers.

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).

The Gregory Optic 48 internal frame backpack is available in your choice of size and color options.
