Whether we're thru-trekking the AT or backpacking our favorite state park the Gregory Zulu 65 Backpack carries all the gear we need comfortably. The FreeFloat ventilated suspension system features a dynamic hip belt that flexes with our body movements for a body-hugging fit that maximizes our comfort when hauling a week's worth of gear on our back. The adjustable torso length lets us dial in our fit while the open-air ventilated back panel and moisture-wicking mesh help keep our back as dry as possible. We especially like the U-zip front panel for easy access to all our gear--even what we've stashed at the bottom of our pack--and the rich array of external pockets from the zippered pockets on the top lid down to the zippered sleeping bag compartment at the bottom of the pack. With a large 65-liter capacity and so much convenient storage this pack is the one that keeps us comfortable and organized on week-long backpacking trips and section hikes in between our re-supply stops on our thru-hike.
